Thanks, aion.
But how cool would it be to have the facility to select "Dynacomp" only (insert compressor circuit to taste), "exciter" only or "both"... ?
A couple of flip-flops + LEDs and associated momentary push-to-make switches, another JFET or 2 (I'd need to work that out), and Robert is one of your parents' siblings. You could have the comp part of the circuit as a daughter-board, so people could choose from a variety or roll their own. A standard Orange Squeezer is a very sweet circuit as is and (having built lots of comps) doesn't seem to have anywhere near the noise associated with a CA3080-based topology (never built a 13700-based one, so I don't have a feel for noise on those). Optos are also nice-sounding... You could have all the components of the switching system on the main board, leaving only V+, GND, Vin and Vout as the only connections needed to the daughter-board.
