I have for sale (4) four matched Audio Research labeled, new old stock 6DJ8, ECC-88, 6922 vacuum tubes. If you're looking to re-tube your Audio Research preamp or line stage these tubes would be an excellent match. Of course, they will also work equally as well in non Audio Research equipment too.
These are high quality Western German tubes which are regarded as some of the best NOS tubes available. The 6dj8 is the American version, Ecc-88 is the European and 6922 is the Russian version of the same tube they are all interchangeable.
I have additional tubes available, so if your looking for more than 4 tubes please email me and I can adjust my price. These tubes are vintage NOS tubes and have never been used. The date code on the tubes are all from 1983. The lettering on the tubes say Audio Research Corporation, 32001100 (Audio Research's part number) ECC-88 made in W Germany. These tubes are part of a 100 tray factory direct lot, so they do not have individual boxes but I will package them in brand new generic tube boxes for shipment. Because the tubes are from the same week of manufacture, they are very closely matched typlically 2% to 5% and I test all the tubes on a mutual conductance tube tester for further matching. I also tested the tubes for shorts and leakage and they passed all the tests. The tubes were acquired from a local collector in the Minneapolis area where ARC is located.

Shipping will be via Fed-ex ground or US post office priority mail. I always carefuly double box all my Audiogon items for shipment. The cost for shipping will be between $9.00 to $10.50 fully insured depending on which carrier you use. I can ship either Fed-ex ground or USPS priority. NO INTERNATIONAL SALES, Continential USA sales only.
For payment I accept paypal and USA post office money orders and personal checks. Personal checks will be held for 4 business days to allow the funds to clear.

If you have any questions about these (4) four NOS Audio Research labeled 6DJ8/6922/ECC-88 tubes please email me.
