Ring Mod

Here’s an idea for a ring modulator. I used a 3080 for the balanced modulator from the Ring-Modu-Matic. I used an envelope, from the Meatball, to control the carrier frequency.

This is untested. The controlling the FET to turn on the carrier is going to be a challenge.

There were a few mistakes in the last version of this. Here’s an updated schematic and PCB.

Here’s a PCB and Layout for the Ring Modu-Matic. I have yet to build this yet so use these files at your own risk! The dual gang pot in the lower corner I can’t get rid of, due to my lack of skills with Eagle. Notice the lines connecting the pot to pads on the PCB.

This is the Ring Modu-Matic from Stompboxology. I redrew everything in Eagle PCB. This is an interesting design. It seems to use several different supply voltages. There is a +9v, +4.5v and +5v, +2.5v,
