TWO super silvertone type 45 tubes

Tubes test 2620 and 2420 where 1100 micromhos is pass/fail

Extra top side mica supports (seen in early 45 st shape coke bottle tubes)

1930's made. One tube is engraved base one tube is ink base but both tubes made in '30s with identical internal mica structure

Hanging filaments

Black plate

Foil getters

Tight firm bases / no rattle no loose parts

NO SHORTS / NO GAS

FULL TEST RESULTS :

-Tube #1= 2620 micromhos and 36.7 mA plate current

-Tube #2= 2420 micromhos and 33.6 mA plate current

% Test Result in Percent %

119% / 110% gm mutual conductance

107.9% / 98.8% mA plate current

For reference:

Tubes Tested on Westmore 501 (Triplett 3444) tube tester where 1100 is pass/fail and 2200 micromhos is Spec(100%) , 34 mA is Spec plate current for type 45 tubes
