I was working on other projects recently, but finally got a chance to work on this. I borrowed the sidechain from @JLM Audio and had a lot of help from @ruffrecords on the tube circuit. The resulting design is nothing all that new, but it is a way to build an inexpensive tube opto compressor. Here's the working schematic:
I think I'm going to design separate PSU and channel cards so (hopefully) two channels can be built into a 2U enclosure. Anyone have any feedback?
Note - I'm intending to use a bicolor LED with SW4B and it's not configured correctly yet.
