No info about availability.
dual LFO with difference rectifier
Two wide ranging LFOs; from approx 830 Hz down to 0.02Hz (1 cycle every 50 seconds), giving tri and square waveforms. There is also a difference rectifier onboard which gives signal corresponding to the positive and negative aspects of the difference between the two tri waves.
All thru holes components, no wiring to do.
These merchants probably sell this module. Huh?
