Sanyo M-7830K

Looking for leads on parts to repair my Sanyo M-7830K. Looks like the function switch has failed. Any ideas on compatible replacement parts?

You can try to disassemble and clean the internal contacts post a picture

Thank you, will be doing the disassembly next weekend. Will upload pictures then, assuming I can get schematics. Sent an email to stereomanuals.com and waiting for a reply on a service manual.

Thank you for sharing the video. Inspiring! I will be doing the disassembly next weekend, if I can get schematics. Sent an email to stereomanuals.com and just waiting for a reply on a service manual.

When I rebuilt that function switch, discovered that those little internal leaf feelers aren't up to the task of switching the power amp. They were toasted. As parts are getting really hard to find, I recommend that you modify the circuit so that the feelers switches a small relay instead to handle the amp current. BTW, AnalogAlley.com has that service manual in PDF format, just FYI.

Thanks for the lead on the service manual. I haven’t heard back from stereomanuals.com.

Thanks I sent Norman a request and he sent me that link on Thursday. Downloaded it and reading it this weekend. Will try to figure out how to create the relay matrix to fit in the book box.
