Fully controllable, pure vacuum tube core, ring modulator.

Unique, pure vacuum tube core, fully controllable, ring modulator. Uses a pair of twin diode vacuum tubes in place of the solid state diodes used to create the ring modulator circuit. This results in a much more analogue, throatier ring modulation effect.

Fully adjustable level for Signal input, Carrier input, Signal Feedback, Carrier Feedbck, Signal to Feedback Mix, and Wet to Dry Mix.

Inputs for Signal, Carrier, Signal Feedback, Carrier Feedback.

Outputs for Raw Output and Mix Output.

Requires 700mA current on startup due to higher current pull from the vacuum tubes. If you do not have the current requirements, an optional 12VDC power supply can be used in conjunction with the Eurorack power supply to provide proper current and voltage.

This module represents the 2024 return of Circuit Abbey to the Eurorack manufacturing community.
