My MC 2205 Amplifier is smoking???


Hello Friends, I am new here because of an inheritance of a Vintage McIntosh System. I will not go to deep down that story again as I already introduced myself. The reason for this post is I received my RCA and Speaker wiring today and couldn't wait to give this baby a test drive to asses the needs.

After some tinkering I was able to get a station to come in clear and a decent volume to come out the speakers.

The good news is, the speakers are worth salvaging with maybe a rebuild and a clean up. THe bad news is the Amplifier is producing smoke. I removed from the Casing, and dusted a bit more, I am hoping it is just because it was sitting for 15+ years.

 

Any thoughts???

 

PS. I am in SO CAL if any one knows a good tech to take on some of this work.

Sounds like dried-out capacitors. I heard that you should use someting called a 'variac' (voltage regulator) that lets you start with zero voltage and slowly increase to normal. You gave it 100% all-at-once which obviously had bad results. Capacitors will "reform" themselves over time if not to messed up.

Another theory is that a mouse made a nest inside the Mac and you ruined his day.
