This Amperex 6922 features gold pins, a D-getter, and a date code of "*0E". Minimum transconductance (Gm) on the Amplitrex tester is 8.8 and NOS tubes typically test around 12.5. This tube tests very nicely at 14.2/14.0.

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).

INTERNATIONAL BUYERS:  Please read and understand the following before making a purchase:

1. First Class Mail can take more than 60 days for delivery, so please be patient. If you need your tubes faster, select USPS Priority Mail or USPS Express Mail.
2. I will not declare a lower value for any reason.
