Hi, my M3 had sparks and smoke coming out, the shop says I need a main power board and a Right power amp and Nad no longer sells parts for that. what should I do?

The real techie can diagnose which parts to be replaced and do that. The one full of snit will tell ya to change the whole thing.
Find real one.

 I did start to wonder about the $ 75.00 diagnose fee and the discontinued parts, they know I have to drive 100 miles to pick it back up. are they conning me?
Where you’re local to?
Technically, I don't have to even open a unit to blast this kind of diagnosis! They did not provide details. It's not sufficient explaination of the cause.
A power supply as well as output stage consists of circuit elements that need replacement.
