Phatt,

Thanks, I'll give it a shot.

I'm new to this forum, but figured I would start here for some answers.

I have an older carpetted Randall RG 100 ES (guessing 80's.) When I try to crank it up a little it plays for a bit, then cuts out and plays at a lower volume.  If I tap it it sometimes it come back, and if I shut it back off for a little and power it back on it comes back.

Any help would be appreciated. It has reverb, presence, bass, middle, treble (with push pull/pot for gain boost), with channel 2 and 1 each with master and gain controls. Also 2 inputs (Lo dB, Hi dB.)
The back has jacks for reverb foot switch, 2 speaker cab outs, signal out, effects send and return, AC out plug, and push button reset breaker. Don't know if you would need to know any of that, but figured more info is better.

Thanks in advance for any help.
