2 RCA/ Jan-CKR Ken-Rad 6L6 Vacuum Tubes

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

***** 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  = 6000 µmhos  

         Industry Bogey plate current = 72mA

                                          Results   = 5800 µmhos ~ 70mA                

                                                         = 5900 µmhos ~ 62mA
