Bulldog, I currently own a 402, and have owned both the 132 and a 7205. You have the makings of a great system that will serve for many years. Bulletproof? What is, but damn close. So the questions and none with intent to insult you: 1)have you checked to assure the SE/Balanced selector is set to the appropriate position.? Also the mono stereo switch. 2) have you tried each speaker output e.g. 2,4 or 8 to assure that none are functioning? 3) it’s been a few years but does the 132 have a zone 2 and if so is it not selected? 4) is the power sentry indicator lit? If so you have a short, you need to check all wires and connectors with an ohm meter.
Now you say the unit powers on, but no response in amplification, with the unit off and unplugged take an ohm meter and check input to output for continuity. Another question, when you power the unit up are you getting any “Hum” or “buzz”? Lastly take the covers off and check that all connections inside are tight, again unplugged.
After all this contact McIntosh and maybe they have experience in this issue. In all my years of owning Mc gear I can attest they are wonderful in service.
Good Luck
