Description
Matched, Tested & Guaranteed Vacuum Tubes
All tubes are guaranteed to be 100% as described or your money back. We are known for our excellent customer service! All tubes have been tested for mutual transconductance, shorts, leaks, gas and noise on one of our calibrated Hickok TV-7 tube testers.
Any pair or quad described as matched means that the tubes will have the same exact construction and will test within a close range of each other for Mutual Transconductance. The last matching criteria is by date codes, which we do match when possible.
