The VT52, a medium-power triode introduced in 1939, also known as “45 Special” is actually a regridded, lower mu, VT25A with an oxide filament and a ST16 bulb. It was used in the Army BC-AS-230 (SCR-183) aircraft transmitter.

The VT52 and the related VT25A were designed to meet the need of the US Army Air Corps to have tubes in airborne radio sets that would give constant output when powered from a generator both at engine idle and at full rpm, a range between about 6.5V and 7.5V.
