These Amperex 7119 tubes are genuine "PQ" tubes made in Holland. The date codes vary, but the interior construction and silk printing appears identical. Minimum transconductance (Gm) on the Amplitrex tester is 10.5 and NOS tubes typically test around 15.0. These tubes measured above NOS spec at 15.8/15.0 and 15.5/16.4.

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).
