Tubes

Transmitting, Receiving, Audio



Disclaimer : All my used tubes have been well tested (sometimes twice). I only sell tubes that test strong and have a good life, I will not sell any marginal tubes.

All tubes come with a 14 day money back guarantee that they test good and are use able. We have stamped all our tubes with a logo for identification so make sure you do not wash off the logo during the 14 days. I will not accept tubes back with out the logo. They will also be extremely well packed.  We test all our tubes on a calibrated TV-7U or Sencore tube testers. Some large transmitting tubes are tested on custom built testers or actual amplifiers. Some audio output tubes are tested with a match maker and I list the IP (plate) current as well as the mutual conductance.
