Prior post reminds me that I need to ask about my 201 amp. Stopped working a few weeks ago. Fortunately I had invested in a spare some years ago (sound of hand patting self on back ) so no interruption of enjoyment. Question is whether it's repairable? It is one of the newer (a relative term at this point) taller, rounded front units. Amp clicks when the power cord is attached and when the fuze is removed and then replaced. Front panel lights up and all functions are fine. Connectors are all solid, but I just get no sound through the speakers. Subbing in the spare and everything works, so it's not the towers. Any suggestions? I did blow this thing up a few years ago (well, maybe more than a few) and Cullen Circuits fixed it for me, but I don't think they're around anymore. Though my electronics skills are limited to running circuits in my house, anything that I could look for inside the chassis?
