RCA JAN 6SL7 GT Vacuum Tube 1944 Very Strong & Balanced ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ***** Tested on our proprietary tester , the E3444 Triplett/Westmore 501 : Its 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 manufacturers 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 manufacturers specified test points or at other specified test points. ***** This tester was prepared by Mr. Paul Hart of Falls Church , Virginia. ***** ********************************************************************* Industry Bogey transconductance = 1600/1600 µmhos & Industry Bogey plate current = 2.3/2.3 mA Results =1640/1700 µmhos ~ 2.0/2.2 mA ????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

1 x JAN-CRC-12SN7gt RCA Tube Made in USA Smoked Glass Military specs Codes H5E = 1944 NOS NIB Tested on Enhanced Triplet E3444 Laboratory Tester by Paul Hart of Roswell Ga. Results =2840/2760 micromhos @ 9.8 / 9.3 mA Bogey (100% or New) = 2600/2600 micromhos @ 9.0/9.0 mA +/- 10% The measurements in this listing were taken on a Triplett 3444 modified to test the tube as an amplifier in accordance with RMA/EIA specifications, utilized by all US and most foreign tube manufacturers. This tester applies test conditions for this tube as shown below (including the precise filament voltage) and then measures transconductance (gm) in accordance with the engineering definition of gm. Tubes may also be operated under the test conditions for extended periods to be sure that it is stable. A tube must be tested in this manner to compare its test results with the manufacturer’s original intent or with other tubes of the same type. Most tube testers do not apply the test conditions required or conduct a valid gm test. For more details on the test and our test equipment, please contact us.The test conditions for this listing are__250_Volts plate, __250_Volts screen, ___-8.0___Volts bias or Cathode resistance* What were your tubes tested at?
