GROUP OF TWENTY ONE (21) VARIOUS 6DJ8 ECC88 VACUUM TUBES AMPEREX MULLARD OTHERS
One additional Amperex added to make 21 (plus the 49 6N23P for 70 total tubes) . See second reply post below.
Cleaning out some more tubes, and I have this group of twenty-one (now) various 6DJ8 types.
Price is $250 for the group, including shipping in the USA via USPS Priority Mail. For shipping outside the USA, please ask for a quote.
These are only for sale as a group.
I tested all the tubes on an Amplitrex AT-1000 connected to a regulated power supply. The tubes were tested in fixed bias mode, and the test cycle was run at least twice for each tube (better warmup time and stabilization).
The spec for “transconductance” (Gm) on the AT-1000 is 12.5 mA/V (12500 micromhos).
Description, date/factory codes and results are below. The date/factory codes are sometimes difficult to see, so they are as best as I can read them. “RT” means right triangle (Amperex/Philips Heerlen factory).

For the purposes of this sale, all of these tubes should be considered
USED.
I have done
no noise/microphonics testing, and I have never used these tubes so I have no idea about sound. I no longer have any equipment that uses 6DJ8 types. Sound is very equipment dependent and personal taste, so please take that into account.
In the addition to the above, I have a box of Voshkod Rocket 6N23P that I screened a long time ago on a different tester (can’t remember which one as I have been through so many testers), and on that tester they tested low on one or both triodes. Not dead – just low (and some very low). When I had 6DJ8 equipment, I actually used some of these low-testing tubes without issue. By my count, there are forty nine (49) of these.
At my asking price as set forth above, I will include these additional 49 6N23P tubes at
an extra $10 no additional charge (making
$260 $250 total shipped in USA for 69 tubes).
I also have a bunch of PCC88/7DJ8 and a number of 6RHH8/6KD8 (a Japanese 6DJ8 variant), so please inquire if interested.
I can provide additional information or photos on request.
GENERAL TERMS AND CONDITIONS
Please note that these tubes are being sold
“AS IS, WHERE IS”. There are no returns or refunds under any circumstances unless I have grossly misdescribed what I am selling.
I ONLY describe what I know about the tubes, and what I have tested for. I may provide test results and, while my tube testers tend to be reliable, YOUR TUBE TESTER MAY GIVE A DIFFERENT RESULT THAN MINE, so please take that into account. In the event of a tube tester conflict, MY TUBE TESTER CONTROLS.
AS SUCH, PLEASE NOTE THAT I CANNOT GUARANTEE (OR EVEN REMOTELY PREDICT) HOW THESE TUBES WILL SOUND OR PERFORM IN YOUR EQUIPMENT. ANY TEST RESULTS ARE ONLY PROVIDED AS AN INDICATION OF TUBE PERFORMANCE IN A VERY LIMITED (AND NON-IDEAL) ENVIRONMENT. EXCEPT AS EXPRESSLY INDICATED IN THIS LISTING, I DISCLAIM ANY AND ALL REPRESENTATIONS, WARRANTIES AND LIABILITY WITH RESPECT TO THESE TUBES, OR RESPONSIBILITY FOR YOUR USE OF THEM.
Payment can be via money order/cashier's check/personal check preferred but, except for US Postal Money Orders, all must clear my bank first. Cash is OK for a local transaction.
I also accept Paypal for convenience (but add 3% to the total in the USA, or 4% elsewhere).
IF YOU PAY VIA PAYPAL, HOWEVER, A CONDITION OF YOUR PAYMENT IS THAT YOU EXPRESSLY WAIVE THE RIGHT TO FILE A PAYPAL CLAIM OR CHARGE BACK (but do retain the right to sue me in court should you so desire).
Shipping terms are EXW US Post Office (INCOTERMS 2010). In accordance with these terms, I will deliver the lot into the possession of the US Post Office, and once in the possession of the US Post Office ALL RISK OF LOSS PASSES TO THE BUYER.
WHAT THIS MEANS IS THAT I EXPRESSLY DISCLAIM ANY AND ALL RESPONSIBILITY FOR DELIVERY (INCLUDING BUT NOT LIMITED TO DAMAGE OR LOSS) BY ANY POSTAL SYSTEM, AND BY PURCHASING YOU EXPRESSLY WAIVE THE RIGHT TO FILE A CLAIM (INCLUDING BUT NOT LIMITED TO BUYER PROTECTION CLAIMS WITH PAYPAL) FOR ANY SHIPPING RELATED ISSUE.
If, however, you have purchased insurance for the item, I will assist to the best of my ability in the processing of any legitimate insurance claim you desire to file.
Trade might be possible, but I have no specific needs. Tubes or a 1TB or greater SSD might be of particular interest. In any event, it does not hurt to ask.
Please check my feedback on Ebay (ID=baileyler) and buy with confidence.
