Description

Silvertone 7025 Vacuum Tube ~~~Strong and 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 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 Roswell, GA ********************************************************************* Industry Bogey transconductance = 1600|1600 µmhos Industry Bogey plate current = 1.2|1.2mA Results =1250 |1375 µmhos ~ 1.83|.90mA Shipping $6 USA No Int'l shipping ***********Thank you **************
