I built yet another JC-2 circuit, this time for stand alone preamp itself. I got old not working Parasound preamp, which I gutted, and put JC-2 circuit in it. What can be more suitable home for JC-2 preamp than Parasound box, both designs by John Curl himself.
To complete the JC-2 preamp, I got 5 input remote control switch with volume control to go with it. Works great. Here are some pictures from the build.
