RCA Developmental Type A5022A Thermally Tuned Oscillator
Oscillateur à accord thermique
Thermisch abgestimmter Oszillator

The A5022A was an early 1-cm oscillator which did not have a tuning triode; however, the external power supply used for heating the tuning mechanism was grid-controlled.
It was used in mid-20th century military test equipment, for example the TS-333/AP, a spectrum analyzer and frequency meter (particularly for continuous wave or pulsed radar signals), used primarily by the U.S. military (Navy and Air Force) starting in World War II.
