MC50 delivered and dropped off at a audio tech right down the street from me here in Austin. He's been working on Macs for 30 years. Convenient!
They looked at me as if I was out of my mind when I asked them about the mods, IEc power connection and replacing the RCA with 1/4" female jack. They said they would not do it because it would be against McIntosh's blah, blah, blah. And it would severely ruin the resale value, duh.
Anyway, they'll check out the caps, resistors, and transistors and have back to me in a week.
Then, I sit and wait for the SMS to arrive. Gonna be a long 6-8 weeks looking at the Mac all by itself.
Once in a while you get shown the light
In the strangest of places if you look at it right.
