There are nine 6V6 tubes in this lot, all of which are indentical in regard to construction. I don't know who made them, but they're clearly from the same manufacturer. I sampled two on the Amplitrex AT-1000 and they both measured 85% of NOS spec. Good and very usable... but not NOS spec.

TESTING: The tube(s) in this sale have been tested on an Amplitrex AT-1000 tube tester (fixed-bias mode), which is a laboratory-grade tester capable of supplying the user with precision measurements. It tests for heater-cathode leakage, gas, mutual conductance, and plate current. Please note that no tube testers are identical and my test results will likely differ slightly from yours.

RETURNS: I will gladly take your tube(s) back for a full refund if you're unhappy for any reason. Yes, it's that simple! Please note that I reserve the right to issue partial refunds if tubes are missing, damaged, or without original boxes (when applicable).
