Theremini not responding to pitch antenna.

Hi all.

I’m trying to help someone whose Theremini stopped responding to the pitch antenna. I was going to check for any loose connections but I can’t even figure out how to open it up! I removed the 4 screws from the bottom but that didn’t seem to help. I did find the schematics online but I’d appreciate any tips on servicing it.

Thanks - David
