Wow, big unit. That doesn't look like it would be a factory power switch.
What is the problem with it.

Should be factory made, I saw same picture onсе. I send it to a technishan. He changed some elements and now is giving 7.8 volts and is not regulating. Hi change on transistor (But i am not shure this is transistor) with simillar- original number (u1b 204- u is underlined). This machine is very old and all elements are difficult for finding.
