***** Tested on our proprietary tester , the E3444 Triplett/Westmore 501 :
It's a Triplett 3444 / Westmore 501 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 accordance 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.
***** This tester was prepared by Mr. Paul Hart of Falls Church , Virginia. *****

Industry Bogey transconductance = 12,500/12,500µmhos &
Industry Bogey plate current = 15.0/15.0 mA
Results =
7600/7000 µmhos ~ 7.5/7.1 mA
7400/7000 µmhos ~ 8.3/6.4mA
