I appreciate any input on this, I have a little electronics experience but not enough to tackle these without a little direction.
Just bought a Fender Ultimate Chorus 2X10 Amplifier. 2 Inputs, Reverb effect built in, etc. Solid state digital amp. Got it home and there was a lot of buzz on the clean and drive channels. About half volume it starts popping loudly. There is a repetetive cracking noise any time I play, but not just sitting. The buzz is there even when nothing plugged into inputs. I took the cover off, removed all the connections and cleaned them and reconnected them, put a nut on the input jack that didn't have one. Found 2 capacitors that had been glued together. The glue was coming loose so I ran a strip of electrical tape between them to hold them from shaking and breaking solders. Put it back together and it sounded great. After playing at 3/4 volume with the gain way up on the drive channel for about 10 minutes, no touching the amp, the crackle came back and it started popping again. I can't figure out where to start testing components.
Also, I have a Prestige 60W PA amp. It runs fine then all the sudden, loses a lot of power and sound quality. I am thinking it is overheating but the heatsinks feel cool. Any input here appreciated.
