Thanks - I am using MX 132 preamp - and signal is coming through to 7205 powering the surround & I have switched up inputs etc. Also the meters are not fluctuating so DOA. I am going to take it to a Mcintosh repair location but I was hoping to do some trouble shooting - the system was very dusty and I have cleaned it out but I thought if it went into fault protect from overheating it may come back of course assuming it did not fry the transformers. Thank you for your response
Mcintosh 402 Amp in protection mode
Bought an entire system of Mcintosh and B&W speakers so I have no history other than the 402 amp that came in the purchase will power on but getting no sound or amplification. I thought these amps were fairly bullet proof so any thoughts or experience on this would be helpful. I assumed extensive repairs in my purchase price - so no surprises.
