Got this Carver amp with C-1 preamp many years ago, probably 1989, second hand. The preamp was fine, but the power amp had some bad transistors. Worked after repair, but had a nasty turn-off pop through the speakers. I'd wince every time I turned it off. Like a full speaker excursion pop. Over the years, especially after about 1993, the two pieces sat in storage. No use at all until the early to mid-2000's, when I tested the stuff and let a friend borrow them for outdoor movie nights at his house. For whatever reason, the turn-off "pop" was gone, and it has been gone. My question is, what's recommended to do to these after so many years? I'm sure it needs re-capped and all the solder connections checked. But anything in particular? And wonder what that pop noise could have been?
Just clean off the residues due to storage, like dust and insects, and leave it alone, if it is working properly.
Carver sets are complex...see the electrolytic capacitors have not leaked, that is all.
But do not attempt repairs unless really needed.
Even experienced technicians are hesitant to do repairs on Carver equipment...
In the meantime, find the schematics and go through them.

Thanks for the replies. I’ll just clean it and check it over. I know it’s a power-on-demand setup through the mag coil, and it’s unusual. Thought maybe something might have been a little off with my repair years ago that caused that turn-off transient, but if it’s happening for anyone else, that’s not likely. It’s played for 30 years without blowing up.
Not advised for powering tweeters!!! 😛
Otherwise, the pop will not harm most other drivers.
Sometimes the pop is actually coming from the preamp, if you are turning everything off at the same time. You could test out the amp by shorting the inputs, connecting a test driver, powering it up for a minute and then switching it off.
I think you can find Carver amp service for sale on Ebay.
