Continuing the project and closet cleaning, and after a lot of stalling, I've finally decided that I won't be using these tubes at all. For those who don't know, these are dual triodes in a 9-pin package and that can work on a plate voltage of anywhere from 6 to 30 volts and so are useful for use in car audio, and other battery powered applications. Tubecad.com also offers a pcboard just for these tubes that can be configured as a preamp, headphone amp, or both simultaneously. These are very rugged tubes, and very quiet and non-microphonic as they were designed for use in a demanding environment.
*SOLD* The first pair is a 60s NOS pair of either holland or west german vintage and a-frame construction -- I'll have to wait until there are some eyes around before I have more details. They are absolutely NOS, tested and matched. Pairs like this typically sell for $70 - $80, but I'll take $60 shipped in lower 48 with no PP fees.
Then I have a bulk lot of mostly Russian made types. These have little to no writing on them except for made in USSR, but have all been tested, though not matched. I have 13 of these and want$90 for the lot -- again, shipped in lower 48 and no PP fees.
PM if interested.
Thanks for looking,
Jim
