Richards MR78 mod includes increasing the tuner's alternate and adjacent channel selectivity, which improves it's ability to pull in closely-spaced channels cleanly.
McIntosh MR78 upgrades?
I have an MR78 that's working well.
I can bring it to Audio Classics, and for about a grand, get the power supply and audio section upgraded, and the tuner will be aligned.
There's another shop, maybe 2 hrs from Audio Classics that does a power supply upgrade for $250, plus an alignment would be billed based on actual time on the bench. So let's say $350-$400.
Is the audio section upgrade worth $600? Would be most interested to hear from people with Mac tuners that have had them modernized.
