Two RCA type 45 tubes

Tubes test 2160 and 2260 where 1300 micromhos is pass/fail

Identical internal construction

Hanging filaments

Black plate

NO SHORTS / NO GAS

Strong +100 gm and mA test results

FULL TEST RESULTS :

-Tube #1= 2160 micromhos and 38.8 mA plate current

-Tube #2= 2260 micromhos and 42.4 mA plate current

% Test results in percent %

108% / 113% Gm mutual condunctance

107.7% / 117.7% 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)
