In my quest for great NOS tubes for my guitar amps, I end up acquiring many tubes that I either don't need or have excessive stock. If I don't have a particular tube listed, please ask. I also have a very large supply of NOS radio tubes from the 1930's to 1970's.

All listed tubes are NOS (new old stock) unless otherwise noted. All preamp tubes are tested on the best preamp tube tester ever made, the Vacuum Tube Valley Dual Triode Characterizer. Preamp tubes are tested for gain, noise, and microphonics. Preamp tubes can also be matched by request, and balanced triode testing can also be done, as well.

All power tubes are tested on the state of the art Maximatcher digital tube tester. All power tubes are checked for shorts, leaks, and excessive current. Power tubes are also double point matched for both Plate Current and Transconductance at 325V and 400V. The Maximatcher is unique in that it tests your tubes at real world plate currents that your amp will run at. Even the best Hickok and other great tube testers of the past won't test your tubes at more than 150V. So there's no way to know if your tubes are matched when running them at higher voltages in your amp. Double point matching also ensures that matching tubes behave the same and will likely age the same way avoiding drift. Please visit my TUBE TESTING & INFORMATION PAGE to learn about my testing equipment, my testing criteria, tube guarrantees, and why you should buy tubes from me rather than dealing with the many significant risks on Ebay.
