Picked up a tip at a repair shop in Austin that saved me hours on old Yamaha receivers

Was down in Austin last month helping a buddy clear out his dad's old shop. Found a Yamaha CR-620 with no sound output. Guy who used to run the place had a note taped to the bench - "check the relay first, not the caps." Popped that relay open and sure enough the contacts were just dirty. Cleaned them with a file and it fired right up. Anyone else run into dirty relay contacts on 70s gear?

That's a solid tip. Dirty relay contacts are super common on those.

Yeah I read somewhere that a lot of older furnace issues trace back to dirty relay contacts. Easy fix if you catch it early.
