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 Tungsram manufactured European tubes which are regarded as some of the best NOS tubes available. The tubes are coded as Ecc-88 which is the European version of the American 6dj8 tube. The 6922 is the Russian industrial version of the same tube. All 3 tube types are interchangeable. NO INTERNATIONAL SALES.
My ad is for 4 tubes total, a matched quad....but if you need more or than 4 tubes email me for pricing. The tubes are matched by transconductance on a Amplitrex AT1000 tube tester which is the current reference standard in tube testers and is widely regarded as the world best tube tester.
These tubes are vintage NOS tubes and have never been used. The date code on the tubes are all from the same week 1982....it's extremely rare to find NOS tubes for reasonable prices with the same date codes!! The lettering on the tubes say Audio Research Corporation, A.R.C. ECC-88 and the lettering is in excellent condition. 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 within 5% for Emissions and I test all the tubes on a Amplitrex AT-1000 reference grade tube tester for further matching. I also tested the tubes for shorts and leakage and they passed all the tests. I also listen to the tubes through my tube tester for noise and they passed the test. The tubes were acquired from a local collector in the Minneapolis area which is where audio research is located.
Shipping will be $6 via US post office priority mail for 4 tubes...for a larger quantity order above 4 tubes shipping will be $11 via USPS or Fed-ex ground. I always carefully box all my Audiogon items for shipment.
NO INTERNATIONAL SALES, No Canadian 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. I will absorb the paypal and audiogon fees.
Audiogon members with no feedback please email me before making an offer to purchase.
If you have any questions about these Four (4) NOS Audio Research labeled 6DJ8/6922/ECC-88 tubes please email me and also If you need a different quantity email me too. Quanities are limited on these tubes as they are NOS tubes. Thanks.
