I have a Yamaha vintage integrated amp. I opened it up, and sprayed out the dust. Someone told me to use contact cleaner on the inside and outside of all the switches and dials.
One of the switches is loose, here's a link to the inside of it (circular thing is the inside), how do I tighten this?
Anything else I should do?

What exactly do you mean by "the switch is loose"? Some of these old selector switches were designed to have a slightly loose feel to it.
I also suggest you apply some deoxidizer/cleaner/protector chemicals, such as the CAIG DeoxIT and/or ProGold.
[btw... does the amp sound "bright"? -- j.k.]

Apparently now the amp's right channel fades out after prolonged use, but turning it off and back on again restores the sound.
Any idea why this might happen?

Could it be heat-related? -- if the sound is restored when you turn it off and then back on immediately (so no cooling down happens), then it is something else. At any rate, this sounds pretty bad...

Just to throw my problem out there, I've got a Marantz 2220B where the right channel cuts in and out. I tracked it down to the Mono button; I can jiggle the hi-pass button next to the mono button and get the right channel back. It's as though the mono button is partially shorting out. Unfortuantely, Rat Shack doens't carry spray in contact cleaner in my area. Dumb question, I know, but where can I find that stuff?

Ken, PartsExpress.com carries all CAIG chemical products, which I can recommend.

I had similar problems with my vintage integrated amp.... I used the Radio Shack stuff - but I wouldn't again. It's content is heavy on the lube, and light on the cleaner. For some things, like pots and switches and buttons, it might be fine in small doses, since the lube will help there - but you will still want a "pure" cleaner to get it clean first.
I guess my point is - count yourself lucky that they don't carry it... it's really not worth it.

Well, I was dense enough to buy a cleaner pen when I was there (feeling desperate), and I've found it to be almost totally useless, except for cleaning Atari 2600 cartridges.
