Hi everyone! I just got one of these with a 4x10 cabinet (it has really nice sounding Eminence Alnico speakers) but the amp has a problem, I suspect a failing filter cap or a problem in the power section.

Does anyone have a schematic for the Randall RG90? I searched the net for a while but only found an old thread here about the topic.

Thanks,
JOHANNES

Although a schematic can help you can still do some testing to work out what has failed.
Maybe give us some more details of what is wrong and folks here maybe able to help.
BTW,,Close up, Clear & well lit pictures can be a big help. (natural sunlight is best) Phil.
