[sdiy] opto compressor project

[JH.]

I've made some pictures of my opto compressor project.
Schematics, too.

Don't laugh at the tube heater circuit - it was a cheap workaround to use
the 26V supply that was intended for a transistor based output amplifier at
first. So at least I didn't have to buy another power transformer with 6 or
12 Volts ...
