L-1 - Tube VCA 1Ж24Б

Voltage controlled tube amplifier based on the 1Ж24Б tube.

1Ж24Б tubes were developed for battery-powered military and space equipment. Since it operates at low voltages and, depending on the switch position, can distort either the negative or the positive portion of the waveform more, it is very well suited for Eurorack modular systems.

The module has two audio inputs and associated attenuators. If only the first audio input is used, the attenuator for channel two acts as a control for the feedback of the first channel. The character of this module reaches from subtle saturation to aggressive distortion and the more the tube is driven, the more mid-range distortions occur.
