TEKTRONIX CURVE TRACER 2. B&K 747 TUBE TESTER 3. MERCURY 1000 DYNAMIC MUTUAL CONDUCTANCE TESTER 4. HICKOK 600A DYNAMIC MUTUAL CONDUCTANCE TUBE TESTER  I test all tubes that I sell in one way or another, or I will state untested. I have a B&K 747 tube tester. This is a mutual conductance tester. It give a percentage value of gm for the tube under test and checks for shorts and grid emissions. I also use a Tektronix curve tracer for testing triodes. I give a number of evaluations for tubes. One evaluation is a screen shot of the tube with a high voltage applied to the plate. This helps the buyer see the linearity of the tube in question at the highest voltage the tube will see in a real circuit. The Curve tracer steps the triode through 10 gate/grid voltages starting with -10 volts and going to 0 volts. The lines show how the tube conducts throughout that range. At 0 volt the tube is at max conduction and is the top line on the display. It is easy at that point to take where that top line intersects the plate voltage, find the milliamp level and compare it to the datasheet. I give those numbers for you in the Item condition box. To further help the buyer I also include the Design values, for gm and ma readings in the table. This can then be compared to other tube sellers using inferior test methods such as Hickok,  Amplitrex, and other testers. The Tektronix curve tracer gives values within 3% of the actual value. The very best portable testers only can approach 10% accuracy. 5.    Please NOTE: The numbers given for gm are what I see on my tester. I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I dont guarantee or imply anything else. 6. VERY IMPORTANT NOTE!!! Vintage tube testers almost always, due to age, have VERY LOW HEATER VOLTAGES!!!  Every tester I have ever bought is below 6 volts when selecting 6.3 volts. They average 5.8 volts. The voltage NEEDS to be 6.3 and 12.6. You can calibrate a vintage tube tester all you want. If the heater voltage is not right, you will NEVER get the right gm value. I have customers complain that their tubes are not the same as what I see on my tester. They say they have a calibrated tube tester. I have 40 tube testers. On all of them I have an outside regulated DC power supply that feeds the tube tester the correct heater voltage. 7. NOTE I dont check each and every tube for noise or tone. This is SUBJECTIVE and it is too time consuming. If you dont like the noise level or the tone we offer a hassle free refund policy.  8. NOTE. TESTING RESULTS SHOW HOW THE TUBE IS PERFORMING  NOW.  TESTING RESULTS DO NOT SHOW HOW OLD A TUBE IS OR HOW MANY HOURS IT HAS BEEN USED. HOWEVER IF A TUBE TEST NOS YOU CAN BE ASSURED IT WILL LAST A LONG TIME AND IS WORKING VERY WELL. NOTES ON CUSTOMER RELATIONS: I want to see you happy with your purchase. I will never sell a tube that is below standard…… I have sold many tubes here on Ebay, and all my customers have been completely satisfied. I will work with you in good faith if there are any problems, or if you are unsatisfied in any way. I want your business now and in the future, so I assume you are the boss, and I am the employee. All tubes are tested for shorts, continuity, and emissions. I prefer PayPal. NOTES ON RETURNS: 1.  NOTE: RETURNS: It is my highest desire that you are completely satisfied with your purchase from me. I will bend over backwards to make sure that you are a happy customer.2. NOTE: We almost always have a replacement available of the same or sometimes even higher quality. Please note that it is our desire TO DO BUSINESS! We never rip anyone off.......EVER. 3. NOTE: If anything you buy from me is less than satisfactory, message me BEFORE you either open a case or hit the “item not as described” button.4. NOTE: Sound quality is tremendously SUBJECTIVE. For tubes returned for noise or sound quality of any kind you pay for the shipping we refund the purchase. We refund the price of the item NOT THE SHIPPING COST. If we sent the wrong tube we will of course pay for return shipping. For any tubes that are DOA we require that you send a us a picture of the shipping box to show us the damage. We test EVERY tube sent out and none should be DOA unless broken in shipping.5.    PLEASE NOTE:  Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily. If you wipe off the silkscreen while handling the tube you diminish their value by up to 70%. DO NOT handle the tubes or hold them from the cylinder. ALWAYS hold them from the ENDS. If you are returning tubes and they are not in the same condition cosmetically I cannot give you a full refund. THIS IS VERY IMPORTANT. 6. NOTE: UNLESS YOU MAKE ARRANGEMENTS WITH US BEFORE YOU PURCHASE, YOU MUST PAY FOR ITEMS PURCHASED WITHIN 2 DAYS OR A CASE WILL BE OPENED FOR AN UNPAID ITEM!!! International customers  NOTE: 1. Please wait for us to invoice you for the correct amount. If you have purchased more than one item, we must calculate how much the shipping will be. Shipping will be HIGHER due to insurance and shipping methods needed for expensive item totals. If you are buying only one item this will not be an issue. 2. NOTE: Under no circumstances will we state on a US customs a declared value of less than the sale price. This is an honesty issue. We are honest with everyone to the best of our ability to do so. We want you to trust that what we say is true. There cannot be that trust, if we make false statements knowingly to anyone. If your country has tariffs/taxes so high that they cause large numbers of normally honest folks to make false statements, we urge you to work for change of those laws. 3 NOTE: International buyers if you bought more than one item and want combined shipping it will ship in 2 days.4. NOTE: And all the Angels sang because the heavenly music was playing and it was turned all the way up.     Listing and template services provided by inkFrog

Here we have 1x Type 12AU6 Vacuum Tube NOS/NOS Testing or Near NOS Testing We have many in stock of various makes. All have been tested on a Calibrated Hickok 800a Vacuum Tube tester. They all test near to or NOS in testing. Some are new old stock in the box, some are used. When you buy one I will just pull one from the box. The picture is a stock photo. Graphics range from Excellent to quite Faded. Thank you for looking Photos Photos shown in this listing are of the actual item for sale. NO STOCK PHOTOS USED unless otherwise stated. All our items, including changeable parts like bulbs, etc are security marked. If an item is returned these marks that have been hidden throughout the unit are checked before any refunds are given. ( sorry about this , but there are those out there that think it is clever to change parts and return faulty ones. In photographs we occasionally use props to display items in the best light possible. These props, like my white board, lighting , kitchen table, Train track, boxes, my left or right hand are not including unless otherwise stated in the listing. ( Sorry for you having to read this but you would be surprised how many people think the items come with my table or a part of my anatomy that I have accidentally caught on camera.) In the first few lines you will see what you are bidding on, i.e... “This auction is for a ?????????? If it does not say base, stand , table , in either the main body of the description or title ... then they are NOT included in the sale. VACUUM TUBE TESTING I do not Sell Just Passable Vacuum Tubes. All tubes purchased have loads of life left in them. Low and weak tubes are unceremoniously thrown in the nearest trash can, unless they are collectors Items. When using the word “Matched” it means in test results rather than in cosmetic looks. Whilst I endeavor to put tubes together from the same year and look the same, this is not always the case. I may have the same tube but from differing years matched up in test results, which means they may cosmetically or internally look a little different... The numbers/letters in parentheses are Equivalents put in to help people to find the correct tube. If it does not say MATCHED then please do not consider them to be such. If you need to know the test results that I get then please just ask. I do not publish test results in the listing as what I get, and what someone else might get can be different. I use a TV7/U military spec Tester which is calibrated. I have 4 of these machines and all display a slightly differing value if I test the same tube, as two testers are never the same. So this shows what I get, and what you get may be slightly different. I also sometimes use a Hickok 752 for testing If I state any values they are for a guide only. All tubes have passed the Gas and short tests. Rectifiers and Diode tubes do not have Transconductance values. Please have a look at the pictures for the cosmetic condition. Please realize when buying antique, vintage or used equipment that they cannot be in an absolute mint or absolute perfect condition, they might need some service, now or later. I take lots of pictures so you can see cosmetics. Use the zoom function and have a good look. It is impossible to describe every scratch, scuff or mark. So take a good look. That is what they are there for. We check and describe the as much of the functionality as we can. If not Fully tested , then items are not tested to the full extent and may have something wrong that I have not discovered. If Fully tested then that is what they are. Fully working. IF YOURE UNHAPPY WITH AN ITEM ... Contact us via messaging. I am human... I make mistakes once in a while. I Run this store on eBay.I am not a huge retail outlet. I try to resolve any issue to both our best interests. MAILING I Try to Mail out within 24 hours of your payment. Where I live the Post office is closed on a Saturday, so Purchases paid for on a Friday will go out on Monday as I work Fridays and do not get home until after the PO is closed. GRADING OF CDs and RECORDS What do the GRADING MEAN? NEW - Unopened and brand new, sealed. Like NEW - Used but no obvious signs of use. ( May be very light Scratching but not noticeable ) ( or the Case/Cover may be Scuffed a little) EXCELLENT- Very light ware to both the CD / Record or CASE/ Cover. Very GOOD PLUS - USED, Some Light Scratching to either the case or CD/Record. Plays Well. Light scratching to the case/ Cover. Very GOOD - USED Light Scratching to both the Case and CD/Record. Slightly Heavier than Above. GOOD PLUS. Light and medium scratching. CD still plays Well . Cover is in Good condition but has normal wear and tear. GOOD. Heavy use. Medium to heavy scratching. CD/Record still Plays ok. May jump or you will hear scratching on the record., or if this is in grading is in regard to the case/Cover then there may be cracks in the case or the cover is Torn , or has rips along its edges or scuffed quite badly. Fair - The CD? Record plays, sometimes skips. Heavy scratching to the disc. In regards to the case or cover, then the case/ Cover is just holding itself together. Poor. CD/Record does not play. In regards to the case/ Cover then this grading means the case or sleeve is badly torn, scuffed, cracked and is falling apart. generally poor condition. Please remember I am not a professional grader. I am quite harsh on what is good and bad. So some items that I may describe as Fair... may be good or above. It is just my opinion and I would rather paint a bleaker picture of something rather than saying it is better than it is. Return policy If in the main body of my listing I sell something AS IS. This means That I have tested something NOT TO ITS FULL EXTENT. Therefore I cannot be 100% sure of its working ability when you get it. In these cases it is best bidding on it as if it was broken. If I say UNTESTED. then I have not test it. Or have only gone so far to test it. I am not like other sellers who say untested and am selling something I know to be broken. I have sold many items as UNTESTED and they have worked perfectly well for the buyer. On the other hand I have sold items that have ended up not working at all. So to recap. You buy items that are untested or Part tested at your own risk. There are NO RETURNS on things I cannot test to the full extent. It is up to you to make a judgment call and decide if it is worth the risk of bidding. FULL REFUNDS ARE AVAILABLE of the purchase cost and original shipping cost if the item you receive is grossly misrepresented or if an item advertised as working arrives in a non-working condition We will pay for return shipping, in some cases. But in most cases the return shipping is the sole responsibility of the BUYER I accept returns unless stated otherwise in the description. We insure everything, and we have to pay for this insurance. I also pack well. If you still receive an item that has been damaged please let us know so we can start an insurance claim. This is a process, and it takes time. I will then gladly refund your money. This is the reason for insurance, and I think it is only fair to ask the carrier responsible for the damage to pay for it. Please be patient enough for this process. If you are demanding your money back and are not prepared to go wait for the insurance process or fail to present the item for the PO or Carrier then it is also only fair you pay for the return shipping because we now cannot claim on the insurance once it leaves you. I am sure you will agree that it defeats the purpose of us insuring anything if no one is going to use the claim process. Should the Claim process fail , for no fault of ours or yours, then we will certainly refund you your money in full. By bidding on this item you agree to these stipulations and to follow the instructions of the post office, or carrier. They will normally want to see the item AND PACKING. If you throw away the packing then this makes the insurance VOID. Thank you for your cooperation and understanding.

Untested tubes. Appear to be new old stock. Mixed types and brands.

Up for auction is a lot of vintage electronic vacuum tubes from Sylvania. There are 9 in the lot with 2 having boxes. The lot includes (1) 12BA6 in box, (1) 12AU6 in box, (1) 12BE6, (1) 6AU6A, (1) 6J6WA, and 4 additional loose tubes. The box conditions are poor and good. Please see pictures. These were all tested with a Test-Tronic TV Tube Checker & Appliance Tester (which I am also selling in another auction). This Tester is also very old so I cant be 100% certain its accurate, but these all came back that they were working. I tested 100s of tubes and there were plenty to show not working as well as working, so there was a least a mix to have some certainty these work. Since these are vintage and I have no actual vintage TV to check them on, these are sold as is. Please make sure to check all pictures prior to buying and message me with any questions. I dont know a ton about these tubes, but I will do my best. Check out my other auctions for combined shipping.

For tubes returned for noise or sound quality of any kind you pay for the shipping we refund the purchase. We refund the price of the item NOT THE SHIPPING COST. If we sent the wrong tube we will of course pay for return shipping. For any tubes that are DOA we require that you send a us a picture of the shipping box to show us the damage. We test EVERY tube sent out and none should be DOA unless broken in shipping.5.    PLEASE NOTE:  Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily. If you wipe off the silkscreen while handling the tube you diminish their value by up to 70%. DO NOT handle the tubes or hold them from the cylinder. ALWAYS hold them from the ENDS. If you are returning tubes and they are not in the same condition cosmetically I cannot give you a full refund. THIS IS VERY IMPORTANT. 6. NOTE: UNLESS YOU MAKE ARRANGEMENTS WITH US BEFORE YOU PURCHASE, YOU MUST PAY FOR ITEMS PURCHASED WITHIN 2 DAYS OR A CASE WILL BE OPENED FOR AN UNPAID ITEM!!!

We are honest with everyone to the best of our ability to do so. We want you to trust that what we say is true. There cannot be that trust, if we make false statements knowingly to anyone. If your country has tariffs/taxes so high that they cause large numbers of normally honest folks to make false statements, we urge you to work for change of those laws. 3 NOTE: International buyers if you bought more than one item and want combined shipping it will ship in 2 days.4. NOTE: And all the Angels sang because the heavenly music was playing and it was turned all the way up.     Listing and template services provided by inkFrog

THIS IS VERY IMPORTANT. 3.  UNLESS YOU MAKE ARRANGEMENTS WITH US BEFORE YOU PURCHASE, YOU MUST PAY FOR ITEMS PURCHASED WITHIN 2 DAYS OR A CASE WILL BE OPENED FOR AN UNPAID ITEM!!! 4. TESTING: I test all tubes that I sell in one way or another, or I will state untested. I have a B&K 747 tube tester. This is a mutual conductance tester. It give a percentage value of gm for the tube under test and checks for shorts and grid emissions. I also use a Tektronix curve tracer for testing triodes. I give a number of evaluations for tubes. One evaluation is a screen shot of the tube with a high voltage applied to the plate. This helps the buyer see the linearity of the tube in question at the highest voltage the tube will see in a real circuit. The Curve tracer steps the triode through 10 gate/grid voltages starting with -10 volts and going to 0 volts. The lines show how the tube conducts throughout that range. At 0 volt the tube is at max conduction and is the top line on the display. It is easy at that point to take where that top line intersects the plate voltage, find the milliamp level and compare it to the datasheet. I give those numbers for you in the Item condition box. To further help the buyer I also include the Design values, for gm and ma readings in the table. This can then be compared to other tube sellers using inferior test methods such as Hickok,  Amplitrex, and other testers. The Tektronix curve tracer gives values within 3% of the actual value. The very best portable testers only can approach 10% accuracy.5.    Please note: The numbers given for gm are what I see on my tester. I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I dont guarantee or imply anything else. 6. VERY IMPORTANT!!! Vintage tube testers almost always, due to age, have VERY LOW HEATER VOLTAGES!!!  Every tester I have ever bought is below 6 volts when selecting 6.3 volts. They average 5.8 volts. The voltage NEEDS to be 6.3 and 12.6. You can calibrate a vintage tube tester all you want. If the heater voltage is not right, you will NEVER get the right gm value. I have customers complain that their tubes are not the same as what I see on my tester. They say they have a calibrated tube tester. I have 40 tube testers. On all of them I have an outside regulated DC power supply that feeds the tube tester the correct heater voltage. 7. I dont check each and every tube for noise or tone. This is SUBJECTIVE and it is too time consuming. If you dont like the noise level or the tone we offer a hassle free refund policy.  International customers note: 1. Please wait for us to invoice you for the correct amount. If you have purchased more than one item, we must calculate how much the shipping will be. Shipping will be HIGHER due to insurance and shipping methods needed for expensive item totals. If you are buying only one item this will not be an issue. 2. Under no circumstances will we state on a US customs a declared value of less than the sale price. This is an honesty issue. We are honest with everyone to the best of our ability to do so.

Lot of 5 NOS NIB Amperex 8426 12AU6 HF94 Vacuum Tubes. $4.45 shipping in the US.

Up for auction is a lot of vintage electronic vacuum tubes from Sylvania. There are 9 in the lot with 2 having boxes. The lot includes (1) 12BA6 in box, (1) 12AU6 in box, (1) 12BE6, (1) 6AU6A, (1) 6J6WA, and 4 additional loose tubes. The box conditions are poor and good. Please see pictures. These were all tested with a Test-Tronic TV Tube Checker & Appliance Tester (which I am also selling in another auction). This Tester is also very old so I cant be 100% certain its accurate, but these all came back that they were working. I tested 100s of tubes and there were plenty to show not working as well as working, so there was a least a mix to have some certainty these work. Since these are vintage and I have no actual vintage TV to check them on, these are sold as is. Please make sure to check all pictures prior to buying and message me with any questions. I dont know a ton about these tubes, but I will do my best. Check out my other auctions for combined shipping.

Here we have a Hickock Branded Matched Pair of Sylvania 12AU6 Vacuum Tubes Boxed Hickok Branded boxed. New Old Stock Please see pictures Thank you for looking Photos shown in this listing are of the actual item for sale.NO STOCK PHOTOS USED unless otherwise stated. Please have a look at the pictures for the cosmetic condition. Please realize when buying antique, vintage or used equipment that they cannot be in an absolute mint or absolute perfect condition, they might need some service, now or later. I take lots of pictures so you can see cosmetics. Use the zoom function and have a good look. It is impossible to describe every scratch, scuff or mark. So take a good look. That is what they are there for. We check and describe the as much of the functionality as we can. If not Fully tested , then items are not tested to the full extent and may have something wrong that I have not discovered. If Fully tested then that is what they are. Fully working. In photographs we occasionally use props to display items in the best light possible. These props, like my white board, lighting ,My Beautiful Wife (she is occasionally caught in the photos), kitchen table, Train track, boxes, my left or right hand are not including unless otherwise stated in the listing. ( Sorry for you having to read this but you would be surprised how many people think the items come with my table or a part of my anatomy and/or my Wifes legs that I have accidentally caught on camera.) Take it from me.... My Wife is not for sale and no amount of money would replace her, though if you offer enough I may include my one of my hands as this would get me out of doing some work. :o) In the first few lines you will see what you are bidding on, i.e... “This auction is for a ??????????

All our items, including changeable parts like bulbs, Vacuum Tubes, circuit boards, internal parts etc. are security marked. If you return an item these security marks are checked before refunds are given. I am sorry for having even to do this , but there are those out there that think it is clever to swap and change parts and return us a faulty item. We have them hidden throughout our items, including internal parts. These are there so we can identify if items have been removed, changed or tampered with when they are returned. VACUUM TUBE TESTING I do not Sell Just Passable Vacuum Tubes. All tubes purchased have loads of life left in them. Low and weak tubes are unceremoniously thrown in the nearest trash can, unless they are collectors Items. When using the word “Matched” it means in test results rather than in cosmetic looks. Whilst I endeavor to put tubes together from the same year and look the same, this is not always the case. I may have the same tube but from differing years matched up in test results, which means they may cosmetically or internally look a little different... The numbers/letters in parentheses are Equivalents put in to help people to find the correct tube. If it does not say MATCHED then please do not consider them to be such. I use a TV7/U military spec Tester which is calibrated . I have 4 of these machines and all display a slightly differing value if I test the same tube, as two testers are never the same. So this shows what I get, and what you get may be slightly different. So all test results are a guide only.I also use a Hickok 752 /800/600 or Amplitrex AT1000 for testing All tubes have passed the Gas and short tests.

What does Checked Tube mean? Tektronix was the leader in high MEGAHZ machines. They were doing some really fast switching. Tektronix was building equipment that was on the leading edge of tube technology. They did things that required careful matching of tube characteristics, such as 18 tube distributed vertical amplifiers. Some of their circuits, by virtue of their being flat from DC to 100MHz, or so required tubes that had unusually stable characteristics. They needed the tubes to meet very high standards in some critical circuits. At times only a single manufacturer made tubes that met those standards.  Because of these special needs, Tektronix had a department dedicated to testing and matching vacuum tubes. They assigned, special part numbers to these highly tested and selected tubes. These tubes were selected by Tektronix for use in critical sections of precision testing equipment. They were hand selected for GM values and balance (within 2% per section). They also were checked for NOISE. They are the lowest noise tubes you can find for the brand selected. That is what the CHECKED STICKER are all about. Tektronix was very picky about the components that went into their equipment.  They made the VERY best test equipment of all time in my opinion.  These tubes are an embodiment of that fact. They sound great in my headphone amp, and they will in yours!  These are a great preamp tubes. Made by GE in the 1960s.  will be exact gm matches.  These tubes must test over 100% and matched to be sold in this auction. I guarantee you will not be disappointed. Normal 0 false false false EN-US X-NONE X-NONE Normal 0 false false false EN-US X-NONE X-NONE On my tester a B&K 747 tester:    Below 55 = BAD      55-65 = ?     65 -100 = Good     100-120+ = NOS         I want to see you happy with your purchase. I will never sell a tube that is below standard…… I have sold many tubes here on Ebay, and all my customers have been completely satisfied. I will work with you in good faith if there are any problems, or if you are unsatisfied in any way. I want your business now and in the future, so I assume you are the boss, and I am the employee. All tubes are tested for shorts, continuity, and emissions. I prefer PayPal. ALL CUSTOMERS PLEASE READ ALL NOTES BEFORE BUYING FROM ME !!1.  RETURNS: It is my highest desire that you are completely satisfied with your purchase from me. I will bend over backwards to make sure that you are a happy customer.If anything you buy from me is less than satisfactory, message me BEFORE you either open a case or hit the “item not as described” button.Sound quality is tremendously SUBJECTIVE. For tubes returned for noise or sound quality of any kind you pay for the shipping we refund the purchase. We refund the price of the item NOT THE SHIPPING COST. If we sent the wrong tube we will of course pay for return shipping. For any tubes that are DOA we require that you send a us a picture of the shipping box to show us the damage. We test EVERY tube sent out and none should be DOA unless broken in shipping.2.    PLEASE NOTE:  Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily. If you wipe off the silkscreen while handling the tube you diminish their value by up to 70%. DO NOT handle the tubes or hold them from the cylinder. ALWAYS hold them from the ENDS. If you are returning tubes and they are not in the same condition cosmetically I cannot give you a full refund. THIS IS VERY IMPORTANT.3.  UNLESS YOU MAKE ARRANGEMENTS WITH US BEFORE YOU PURCHASE, YOU MUST PAY FOR ITEMS PURCHASED WITHIN 2 DAYS OR A CASE WILL BE OPENED FOR AN UNPAID ITEM!!!4. TESTING: I test all tubes that I sell in one way or another, or I will state untested. I have a B&K 747 tube tester. This is a mutual conductance tester. It give a percentage value of gm for the tube under test and checks for shorts and grid emissions. I also use a Tektronix curve tracer for testing triodes. I give a number of evaluations for tubes. One evaluation is a screen shot of the tube with a high voltage applied to the plate. This helps the buyer see the linearity of the tube in question at the highest voltage the tube will see in a real circuit. The Curve tracer steps the triode through 10 gate/grid voltages starting with -10 volts and going to 0 volts. The lines show how the tube conducts throughout that range. At 0 volt the tube is at max conduction and is the top line on the display. It is easy at that point to take where that top line intersects the plate voltage, find the milliamp level and compare it to the datasheet. I give those numbers for you in the Item condition box. To further help the buyer I also include the Design values, for gm and ma readings in the table. This can then be compared to other tube sellers using inferior test methods such as Hickok,  Amplitrex, and other testers. The Tektronix curve tracer gives values within 3% of the actual value. The very best portable testers only can approach 10% accuracy.5.    Please note: The numbers given for gm are what I see on my tester. I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I dont guarantee or imply anything else.6. VERY IMPORTANT!!! Vintage tube testers almost always, due to age, have VERY LOW HEATER VOLTAGES!!!  Every tester I have ever bought is below 6 volts when selecting 6.3 volts. They average 5.8 volts. The voltage NEEDS to be 6.3 and 12.6. You can calibrate a vintage tube tester all you want. If the heater voltage is not right, you will NEVER get the right gm value. I have customers complain that their tubes are not the same as what I see on my tester. They say they have a calibrated tube tester. I have 40 tube testers. On all of them I have an outside regulated DC power supply that feeds the tube tester the correct heater voltage.7. I dont check each and every tube for noise or tone. This is SUBJECTIVE and it is too time consuming. If you dont like the noise level or the tone we offer a hassle free refund policy.  International customers note:1. Please wait for us to invoice you for the correct amount. If you have purchased more than one item, we must calculate how much the shipping will be. Shipping will be HIGHER due to insurance and shipping methods needed for expensive item totals. If you are buying only one item this will not be an issue. 2. Under no circumstances will we state on a US customs a declared value of less than the sale price. This is an honesty issue. We are honest with everyone to the best of our ability to do so. We want you to trust that what we say is true. There cannot be that trust, if we make false statements knowingly to anyone. If your country has tariffs/taxes so high that they cause large numbers of normally honest folks to make false statements, we urge you to work for change of those laws.3 International buyers if you bought more than one item and want combined shipping it will ship in 2 days.4. And all the Angels sang because the heavenly music was playing and it was turned all the way up.    Listing and template services provided by inkFrog
