I have for sale a quad (4 tubes) of Audio Research labeled W. German 12ax7 tubes. The tubes are tested on an Amplitrex AT-1000 reference tube testers variable setting. These are the very desirable smooth plate 12ax7 tubes.
These are early 1980's vintage NOS (new old stock tubes) that are part of a 100 tray factory lot. Because the tubes are part of a factory tray they were more than likely all manufactured on the same day.

The tubes have always been stored in a smoke free, temperature controlled environment. The lettering is strong on the tubes but fragile due to age.
The silver flashing material on the top of the tubes are in excellent shape, two of the tubes have small dark spots in the flashing material caused in the manufacturing process. The tubes pictured are from the 100 tray lot and are an example of the lettering. The tubes will come in generic white tube boxes. You get four tubes for my listed price. Audiogon does not have a New old stock category so they are listed as mint condition because they are NOS and unused.

All the tubes are tested, matched and listened to for noise on a state of the art, Amplitrex AT-1000 tube tester using the auto mode. The test results are 90/95, 90/90, 90/90, 95/90 for emissions where anything over 85 is considered excellent for a NOS tube, the GM rating will be well over 100 for all the tubes in both sections. I've had a quad of these tubes in one of my ARC preamps for awhile and I'm very impressed with their excellent sound and low noise. Like most NOS European tubes such as Mullard and Telefunken the tubes flash when energized and this is normal for this tube type, due to the special filament design.

I've had multiple repeat buyers of these tubes from audiophiles and studio/touring musicians on this site and other sites that I list on.
Shipping will be $3.75 shipping via USPS first class. I carefully box, all my tube shipments. NO INTERNATIONAL SHIPPING. Continental USA sales only
