What we do (in one sentence)
We offer quality tested current production & NOS vacuum tubes for guitar amplifiers and high-end audio applications.
Our Services
Every tube gets:- 1. Burned In
- 2. Tested
- 3. Matched
» Burning In
All power tubes are burned in for 24-48 hours using a pair of Maxi-Burn rigs that each burn in 30 tubes at a time. Burning the tubes in stabilizes the tube, which ensures a more accurate reading for when we match the tubes.
» Testing & Matching
Preamp Tubes
Every tube is tested on a Vacuum Tube Valley dual triode characterizer. We guarantee that every preamp tube we offer is tested thoroughly for proper gain, low noise and microphonics, and overall quality.
Power Tubes
Like the preamp tubes, every power tube is thoroughly tested under conditions that recreate the circuit for which it is intended. Power tubes are matched for plate current draw and transconductance using a Maxi-Matcher digital tester, or our Multi-Matcher(which does 30 power tubes at once). All power tubes are tested for microphonics, durability, and overall quality.
