2 Type 1A4 Vacuum Tubes

RARE 1930’s Vintage RF Pentodes

These used tubes have been tested for mutualconductance. On my Hickok TV-7 tester they read 25 and 27. A reading of 19 would represent theminimum recommended value. These used tubes are from 1930’s USA production.These bases and grid caps are tight with no rattles.

The 1A4 is a receiving remote-cutoff pentode with alow drain 2-volt, 60-mA filament. This tube type was used in many types ofportable radios from the 1930’s and 1940’s.
