Maestro RM-1A Ring Modulator

 A requested circuit but bear in mind that it is rather big, has an onboard charge pump for 15v-15v operation, and has a quite complicated setup due to five multiturn trimmers.

I've omitted the (for now) the Osc, Pitch, Carrier and Modulation jacks but might add it later on if is requested but it will be an "offboard wiring extravaganza".

 Schematic is avaiable HERE
