Two KEN-RAD type 45 vacuum tubes
Tubes test at 2270 and 2100 where 1300 micromhos is pass/fail
Hanging filaments
Black plate
Foil getter
NO SHORTS / NO GAS
No rattle / no loose parts / tight bases
Clean pins
FULL TEST RESULTS :
-Tube #1= 2270 micromhos and 32.2 mA plate current
-Tube #2= 2100 micromhos and 28.3 mA plate current
% Test Results in Percent %
113.5% / 105% gm mutual conductance
89.4% / 78.6% mA plate current
For reference:
Tubes Tested on Amplitrex AT-1000 computerized tube tester (fixed bias mode)
For reference:
Type 45 tubes: Spec (new) = 2000 micromhos and 36 mA plate current
Type 45 tubes: 1300 micromhos and 23.4 mA = pass/fail grade (65% of Spec value)
