so while trolling craigslist for amps, i've found a fender super 60, the ad says its from 1988 w/ new sovtek tubes. I'm definitely considering buying it, the youtube vids sound GREAT. So whats a fair price for one of these? hes got it listed at 320$ i figured 300$ will take it. And since its an older tube amp and im not a really experienced buyer is there anything i should look for other than the fact that it turns on and makes noise?
They're almost like a budget tube amp. I like the sound a lot, nice amps!

Great price/sound ratio for sure.

I own one, it's a very nice amp especally for 300$
The only thing I don't like about this amp is that it's impossible to bias easilly.
