Hi all, new to the forum.
Just picked up a 5210 from 88 and it plays fine for a few minutes then goes into this really loud 60 cycle hum. Its like you have everything cranked all the way up with a single coil plugged in. This can be turned down with the master v. But not the preamp volume. Also cord plugged in or not makes no difference.
To me it seems like the preamp is taking off on its own generating signal or a transistor has latched full on.
Any ideas?
