I have for sale (8 ) eight Audio Research labeled new old stock 6DJ8, ECC-88, 6922 vacuum tubes. If you're looking to re-tube your Audio Research preamp these tubes would be a great replacement to your old and worn original tubes. A fresh re-tube can have immediate sonic improvements...these tubes will also work equally as well in non Audio Research equipment too.
If your looking for more or less than 8 tubes email me and we can discuss options. Please note, the ad is for 8 tubes total... do the research and you'll see it's a good price for NOS tubes these are the most popular 6dj8 tubes I offer for sale.
These are high quality Western European tubes which are regarded as some of the best and lowest noise NOS tubes available. The tubes are coded as Ecc-88. The 6dj8 is the American version, the ECC-88 is the European version and the 6922 is the Russian industrial higher output version of the same tube. All 3 tube types are interchangeable. These tubes are vintage NOS tubes and have never been used or installed. The date code on the tubes are all from the same week 1983 and all from the same factory. It's very rare to find NOS tubes with the same date codes!!! Quantities are limited on these tubes so if you've bought these tubes from me in the past nows the time to get a second set for storage. No International sales, Continential USA sales only.
The lettering on the tubes say Audio Research Corporation, 32001100 (ARC's part number) made in W. Germany, ECC-88. These tubes are part of a 100 tray factory lot, so they do not have individual boxes but I will package them in brand new generic tube boxes for shipment. The tubes test as new and are matched like the manufacturer does which is for transconductance or the GM rating. The GM rating will all be over 100 for the tubes and they will be withing 5% for the GM on both sections...I test the tubes and listen to them on a Reference quality Amplitrex AT-1000 tube tester..
Shipping will be $7.00 using usps priority mail. NO INTERNATIONAL SALES, CONTINENTAL USA Sales only.
Audiogon does not have a NOS rating so they are rated as mint as they are new tubes never installed in equioment
For payment, I accept paypal. Also, check my feedback on previous tubes and purchase with confidence.
