broken piece of audio gear and just assumes you are accepting donations today? A couple of years ago I sold a Yamaha integrated, much newer than this, to a fellow that wanted it for his shop. His amp had died and he just wanted something else that worked. I had forgotten about the details of this exchange other than I now remember telling not to throw it away as it was a nice amp. He is a cabinet maker and I kept his contact info because I thought I would be remodeling my kitchen sometime soon. So, I called him about a week ago and he came yesterday to talk over my project AND he brought the old Yamaha with him. It was a bit ratty with a few chips to the veneer and some sort of smutz spilled on the top rear of the case.
Anyway he said one channel was out, so I assumed it would be a power amp section. I wiped the case with a damp rag and the smutz seemed to soften so a taping knife scraped it right off. There is a bit of a darkened/stained area but not so bad. I had some hope that maybe the amp/preamp bridging switch or another control might be the culprit for the "no signal" in one channel. So far I've found that the power amp works fine so I guess I'm looking in the preamp section. I still hope it will just be a dirty control. Might also be a power supply issue but I assume this would be common to both channels.
I'll clean all the controls of course, but anyone have any other common issues with the preamp section to recommend? As with so many things like this, I don't need it (already have one actually) but how can you just let something like this go without attempting to make it right. I offered to fix it for him but he said he didn't need it. I should just turn it around and move it along, but I have a hard time doing that. I want to fix every piece of audio gear that lands in my lap. It's sick. I'm really a tube guy but I love to see things get fixed and remain useful and enjoyable.
Thanks for listening,
John
