*NOTE: The last pair in the listing is dated 3E1 and 3D1.

THESE TUBES HAVE BEEN CURVE TRACER MATCHED. THE CURVES SHOWN IN THE PICTURES ARE OF EACH TRIODE. EXAMINE THE CURVES FOR LINEARITY. THE gm PERCENTAGES IN THE TABLE ARE FROM THE B&K 747B I USED FOR NORMAL TESTING.

CURVE TRACER MATCHED!!! TESTING ACCORDING TO DATA SHEETS FOR 6DJ8’S ARE AS FOLLOWS: 90 PLATE VOLTS, MARGINAL GOOD 65%: 21.4ma, LOW NOS 85% = 28ma, NOS 100% = 33ma. 

THIS PAIR MEASURES: 34, 35, 34, 35ma.

This is a pair of  GA7 Bugle boys. These tube are generally found in sockets that have a critical function and are generally very well balanced when tested. This pair is no exception to that being perfect in balance and match.

 They were in a piece of precision electronic equipment that sat idle since 1963. All of the tubes test at NOS levels. It's like they were sitting in a secure vault waiting for me! The silk screen is perfect and they are in almost perfect condition. They will sound sweet!!! They will not last more than a few weeks and they will be gone. Get them while you can.

All of the tube pairs are above the NOS line on my tester and will be well matched. I guarantee that you will be pleased with these sets. I have a 100% satisfaction rating because I make sure my customers are happy. That is my number 1 concern.

This is what TUBE WORLD says about O getter BUGLE BOY tubes: " (This is a very good audio preamp tube; very detailed, good base definition, punchy midrange, has warmth, instruments sound very natural, excellent vocal reproduction, recommended) (The best sounding 6DJ8 are made in Holland and Germany, these sound superb in the HEART tube CD player)" - 

On my tester a B&K 747 tester:    Below 55 = BAD      55-65 = ?     65 -100 = Good     100-120+ = NOS 

I PERSONALLY purchase, clean, identify, test, and stand behind every tube on this site. I have a small company. You will deal with me personally.

I want to see you happy with your purchase. I will never sell a tube that is below standard……I destroy those tubes. I will not sell a tube that I feel will not last or has been abused. 

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.

If you want a return for any reason, I will give you back 100% of your purchase and any shipping you paid.

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.    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 don't guarantee or imply anything else.

5. 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.

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.
