This is a tube based Voltage Controlled Amplifier / timbral gate. While this module basically operates as a VCA, it does add a degree of distortion to the signal. How much distortion depends on how hard it is driven.

Add feedback and it begins to oscillate, synchronizing, to some extent, to the incoming signal.

All this while running on a standard synthesizer power supply, with no extra heater supply required.
