Never come across this make before. Anyone by any remote chance got a set of schematics for an 'El Diablo 60' or similar model. Only user manuals on their website, and I can't find any of their schematics on all my other 'usual suspect' sites. I need to fix this on the hurry up - by the weekend if poss. It suffered spike damage from a nearby lightning strike when the owner was playing at a recent outdoor gig.
Amp basically works ok, but unable to select between "Warm" and "Hot" channels, either with the front panel switch or the footswitch.
TIA
