Sharp-Cutoff Tetrode
The 32 Vacuum tube is a screen grid tube recommended primarily for use as a radio-frequency
amplifier. It contains a coated filament which takes as little power as possible consistent with
satisfactory operating performance. This feature makes the '32 particularly suitable in
battery-operated radio receivers employing the '34, '31, and/or '33 where economy of filament
current drain is important.
