Product Description

Matched, Tested & Guaranteed Vacuum Tubes

All tubes are guaranteed to be 100% as described or your money back. All tubes have been tested for mutual transconductance, shorts, leaks, gas and noise on my calibrated Hickok TV-7/U.

Any pair of 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 criteria is date codes, which I do match when possible.
