Description
This Amperex VT-4C tube features a brass base, square getter, and black plates. I would assume it was produced during WWII. Minimum Gm is 2.5 (mA/V) and NOS spec is 3.6. This tube measured at 5.0 with a plate current of 136.8mA. While the test results are very good, the tube has some intermittent static noise. For this reason, it is being sold at a discount and as-is with no returns allowed. TESTING: The tube(s) in this sale have been tested on an Amplitrex AT-1000 tube tester, 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. The AT-1000 is also used to screen for unwanted noise and microphonics, which is something very few eBay sellers do! Please note that no tube testers are identical and my test results will likely differ slightly from yours.
