TESTING ACCORDING TO DATA SHEETS FOR 6DJ8’S ARE AS FOLLOWS: 90 PLATE VOLTS, MARGINAL  THIS PAIR MEASURES: 35, 34ma.  THIS IS A REAL WORLD TEST OF THE TUBE. We tested it with the same voltages it will see in a real application circuit. Most testers cannot put the proper plate voltages on a tube and cycle through stepped grid voltages like we do with 576 CURVE TRACER. OK, here they are......these are the tubes you have been looking for! These are MULLARD 6DJ8s. For audiophiles these tubes are the sweetest sounding tubes made.  Once they are gone I have NO MORE. These tubes are perfect for use in the  Lampucera1.0 + Lampizator CS8416 + CS4397. This guy does some fantastic work in taking the signal straight out of a DAC and before it get mucked up by the OPAMP he steals the pure analog signal and routes it to the 6DJ8.  The signal can then be fed into you headphone am for pure sound. AWESOME!!! 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. 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. 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

SUPER RARE LARGE GLOBE MULLARDS!!! These particular tubes are rare. Of the thousands of Orange Globes tubes I have sold, only a handful have been made in England using the Bugle Boy/Orange globe insides. Most England tubes have an a-frame construction. These are the HeErlen type insides. Very rare and very sweet. It would be like finding a gold doubloon on the beach to see these beauties again. I will accept no offers on these tubes. 99.99 or I keep them for me. BLACKBURN examples of tube perfection. These pairs are super strong testers. Sonically they are AWESOME! I listened to them for hours, Led Zep, Pavarotti, Tony Bennett, Barry white. These tubes deliver the goods. I compare them to Siemens and Telefunkens. Very tight Highs. The warm but most accurate mids. A little bass compression but not bad. Absolutely no microphonics! Heres what Joe of Joes Tube Lore has to say about these tubes: Mullard 6DJ8, Great Britain (shield, steel pins) One of my pair of these died a year ago (moment of reverent silence please....) so I couldn’t compare it directly to the others in this shoot-out.

I get lots of e-mail from people asking questions that are fully answered on the page. You can also help me by researching the item on Google or Ebay. I am not an expert on the items I sell. Be sure to check out my other similar auctions. Most of the items I sell have been in storage or in houses for many years and as a result may have odors, such as mildew, mold or smoke. If you win more than one item from me, please wait for an invoice. If you are bidding on more of my items that are ending soon, send me a message. Bid retractions: You may ONLY retract your bid if you accidentally bid the wrong amount. For example, you meant to bid $20, not $200. In this case, You MUST enter the price you intended to bid as soon as youve retracted the incorrect bid. If you wish to retract your bid and do not intend to place the correct bid, please send me a message explaining your situation. I report and block bidders who abuse eBays bid retraction policy. Tubes test good. Please see image(s) for details. Items are generally shipped quickly. If you have special packing or shipping requirements or suggestions, you MUST contact me before sending payment. Its not fair to me when buyers send the payment with a note to double box the item or flatten the box. While I am happy to accommodate such requests, they add size and weight to the package and increase the shipping cost. International bids are welcome on most items. Do not even think about asking me to declare it as a gift or the value of an item less than the sale price. All customs forms will be accurately filled out. When you check out, you can pay using Visa, Mastercard, Discover, PayPal, PayPal Credit, Apple Pay (through the eBay app and mobile website only,) Google Pay (through the eBay app, mobile website and desktop,) local pickup and other mutually agreed on methods. If you check out through eBay, the item will be shipped to the name and address that you used. If you have moved or wish to ship to another address, update your shipping information with eBay before you send payment. I have made and do make mistakes. I use eBay’s shipping calculator - if I enter the incorrect weight or dimension, the shipping difference could be significant. If that does happen, let me know ASAP so we can make things right. I don’t pack boxes in advance to get exact weights because I offer combined shipping. I try to charge only actual shipping cost. Please be fair to me and all eBay sellers and at least give us a chance to fix problems before you start a return, leave feedback, make eBay claims or leave detailed seller ratings. Final word - I want ALL my customers to be satisfied, so if you are not, e-mail me before you leave feedback or file a claim and give me a chance to make you satisfied. Good Luck!
