RCA 6922 E88CC 7308 Gold Pins Vacuum Tube Very Strong & Balanced ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~**** Tested on our proprietary tester , the E3444.
It's a Triplett 3444 that has been enhanced.
This tester uses regulated power sources for the bias, plate, & screen voltages, as well as modified operating & testing procedures.
Filament voltage is also controlled.
Tubes are tested in a...ccordance with the manufacturer's specifications; measurements closely align with a laboratory tester built to rigorously measure vacuum tube characteristics.
Tubes can be accurately matched for gm & plate current at the manufacturer's specified test points or at other specified test points.
