6BS8 Vacuum Tube, Tung-Sol, Used, B&K 707 Tested: Good Testing procedure: Each tube has been tested for dynamic mutual conductance on my B&K 707 tube tester, as well as screened for shorts and leakage. They are then subsequently subjected to the 707s Life Test, which offers an indication of remaining useful life. A Life Test reading very near or greater than the mutual conductance reading indicates a tube in excellent condition, and will be presumed NOS absent any contrary evidence. For reference, B&K describe a life reading of 25% below the mutual conductance test to be nearing the end of its useful service life. Ive labeled each tube box with a sticker indicating its test results. M for the mutual conductance test, L for the life test. The meter scale runs from 0 to 120, so any indication beyond that will be marked 120+. It should be noted that units for both measurements are undefined (not Mu, not Gm,) and are only technically useful in recording how a given tube tests on a B&K 707. Returns, Troubleshooting, and Liability: All tubes (unless explicitly sold for parts or not working.) are guaranteed to arrive in good working order, as tested and described, or else may be returned, replaced, and/or refunded. Any tubes in this listing have been tested per the procedure above above, unless otherwise noted. That said, the best test for a tube is real life service. Its also true that lots of tube equipment is old and in need of repair well beyond new tubes. If a tube Ive sold you fails to meet expectations, please do due diligence to determine if it is really the tube, or rather the surrounding equipment which is at fault. Sometimes equipment will damage tubes, and sometimes tubes will even damage equipment. While I can guarantee a tube is short-free when I ship it, I cant guarantee it will remain that way forever. In that respect, you must use these tubes at your own risk. I also expect that anyone purchasing vacuum tubes is familiar with, and able to safely navigate their inherent hazards, including but not limited to the possibility of implosion, electric shock, exposure to heavy metals, and radiation. Shipping: Shipping is buyer-paid, and determined by location, package volume, and weight. Combined shipping discounts are automatically available for almost every item, but only if purchased in a single transaction (all in the same shopping cart.) While the automatic combined shipping discount is quick and easy, if you would like, feel free to request an invoice prior to purchase for an as-packed shipping quote, which may be less expensive. Payment: Payment is expected within 4 calendar days of your purchase, unless you notify me youre holding out for combined shipping. I can only accept payment through eBay.

  TUBE HUNTER VACUUM TUBE GEMS THESE ARE THE SPECIFICS OF THE TUBE/TUBES FOR SALE THESE ARE THE TUBE/TUBES FOR SALE:    MANUFACTURER:                               RCA PRODUCTION CITY:                                     USA TUBE TYPE:    6BZ7 DESIGNATION:                                             PENTODE TRIODE YEAR:    1959 MONTH:    JULY Date code match    YES SILK SCREEN CONDITION %:                    100% MICA:    2 PLATES:    BLACK GM %:     120% 118% AND 119%, 118% SINGLE/PAIR/QUAD/MULTI:     PAIR GETTER:                                                          WIDE D GETTER DATE CODE                                                  KY On my tester a B&K 747 tester:    Below 55 = BAD      55-66 = ?     65 -100 = Good     100-120+ = NOS   STOCK PHOTO 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

LISTING WILL GENERALLY HAVE INFORMATION ABOUT ANY BOXES ASSOCIATED WITH THE TUBES FOR SALE. THESE ARE THE OPTIONS: 1. ORIGINAL BOXES IN VARYING CONDITION. THESE BOXES WILL BE THE ORIGINAL BOXES THE TUBES CAME IN AND WILL SHOW AGING IN VARYING DEGREES. THESE TUBES ARE ASSUMED TO BE NEW AND WILL TEST AS NOS. 2. NO BOXES PROVIDED (NONE AVAILABLE USUALLY USED AND SHOULD BE ASSUMED TO BE USED UNLESS OTHERWISE STATED. 3. REPURPOSED BOXES. THESE ARE BOXES OF THE SAME MANUFACTURER. THESE WILL HAVE A LABEL OVER THE TUBE NUMBER THAT REFLECTS THE TUBE BEING SOLD. THESE TUBES SHOULD BE ASSUMED TO BE USED UNLESS OTHERWISE STATED. 4. TUBEHUNTER BOXES. THESE ARE BOXES I HAVE MADE WITH GREAT TIME AND EXPENSE TO PROTECT YOUR VACUUM TUBES AND PROVIDE FOR STORAGE AND EASY IDENTIFICATION. TUBES IN THESE BOXES SHOULD BE ASSUMED TO BE USED UNLESS OTHERWISE STATED. 5. WHITE BOXES. SHOULD BE SELF EXPLANATORY. NOTES ON TESTING OF TUBES: THIS IS DONE ON A NUMBER OF TESTING DEVICES 1. 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!!! 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.  8. 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.  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. 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. 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. 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.  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. 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
