THESE TUBES ARE BECOMING VERY RARE. MADE FOR CBS BY SIEMENS CORPORATION IN MUNICH GERMANY IN 1959-61!!! I PUT THESE IN MY HIFI AND LISTENED TO MY MILES DAVIS KIND OF BLUE. BIG CHECK MARK FOR ..........YES!!!NOTE: SOME PAIRS WILL BE 1958, 1959, 1960, or 1961. ALL ARE THE SAME CONSTRUCTION AND EACH PAIR WILL BE DATE MATCHED. Here is a pair of SIEMENS 6DJ8s. These tubes are in NOS shape and test NOS. The equipment they were pulled from was dust free which means it saw little use. That means they were on the the shelf waiting for me and you for the last 50 years. Man do these sound wonderful. Im listening to MILES DAVIS right now as I type this. This is one of my got to albums to test what the tubes deliver, and these Siemens are AWESOME! You have to wonder.....how do they do that? Why do tubes sound SOOOOO much better than solid state? I know the technical reasons, but it still is amazing every time I put on the cans. I have to say something about the underrated Siemens steel pin tubes. These tubes were made by Siemens in the 1960’s and early 1970’s. They were made in the Siemens factory in Munich Germany. These tubes are EVERY BIT AS GOOD as the vaunted Telefunken tube. The sound signature of these tubes is marvelous. Wispy light ethereal highs that tickle the inner ear, and a most honest detailed mid range that describes the event with stunning clarity. Don’t forget a crisp, but well rounded bass signature and you have these tubes preforming in the same vane as any other German made tube. They are precise and clean with no nonsense. Telefunkens go for 175 a pair. These Siemens gems go for 89.99 and deliver as much or more. This pair was made in MUNICH and carries the CBS label. 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 tube are an embodiment of that fact. They sound great in my headphone amp, and they will in yours! On my tester a B&K 747 tester: Below 55 = BAD 55-65 = ? 65 -100 = Good 100-120+ = NOS NOTES ON THE BOXES. LISTING WILL GENERALLY HAVE INFORMATION ABOUT ANY BOXES ASSOCIATED WITH THE TUBES FOR SALE. THESE ARE THE OPTIONS: 1. NO BOXES PROVIDED (NONE AVAILABLE USUALLY USED AND SHOULD BE ASSUMED TO BE USED UNLESS OTHERWISE STATED. 2. 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. 3. 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. 4 WHITE BOXES. SHOULD BE SELF EXPLANATORY. 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 INTERPRETATION OF RESULTS: NOS = 80% TO 135% GOOD = 65% TO 80% ? OR MARGINAL : 55% TO 65% BAD = 55% 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. 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
