I'll take out the one that's in there, stick a socket in, and then reverse it and see what happens.

The 78L05 did get pretty hot when I was troubleshooting another problem, so it could definitely be backwards.

In trying to follow the help rules... The only parts substitution I may have made was using a 78l05 in place of the 7805.

Good to know that there's one less problem to trouble shoot.

I got out the signal probe. I got audio going in at pin 20. At pin 14, when the play button is off, it's silent. when the play button is engaged, it makes the static sound. I'll post pictures as soon as I find the camera.

I have a back up IC3, would it be worth it to just try switching the chips?

I've finally finished assembling the loophole, but I'm having some issues with it. If the record switch is engaged, both the record light and the play light are both on. Additionally, when just the play switch is on, it plays back just a loop of static (it's definitely playing "something" back though).  The filter, vol and dry knobs all seem to be working fine.

I'll post gutshots in the morning and also try to see what signal I'm getting at pin 20.

Thanks for posting that image. I've been meaning to repair a Russian Big Muff I've had laying around for years, and now I have the info to do it.
