Bought an old Rickenbacker TR25 guitar amp about a year ago. After a few months I noticed that there was a quiet distortion audible in addition to the clean signal. More noticeable at lower volumes. Someone suggested replacing the power supply caps, which I did, but that little bit of distortion didn't go away. Not worse, but not better either.
Left the amp alone for a few months, when I came back to it, it now makes an awful squealing and static noise. The noise increases as the volume is turned up and is silent when the volume is at zero. I haven't opened it up yet to check where I worked on it before, but I figured that should be the first thing I check. If not, any ideas what else it could be?
