Vintage McIntosh Question

Audio Classics near Binghamton,NY will service them for you.

I asked the same question of McIntosh, here is their response.

Hi Bill,

Nope there are no upgrades, they are still awesome units.

I tend to agree with the responses here.

I have 2 service centers within a reasonable driving distance.
Electric Clinic in Gaithersburg, MD & Music Tech in Springfield, VA. Anyone have any experience with either?

you may know, but DeWick is the best....

Audio Classics. These guys are ex Mac employees and they can even take you on a tour of the Mac factory. I stopped by there a few years ago and was flabbergasted at their operation. Tour busses full of Japanese tourists stop by this place. The amount of Mac gear sent to Japan is amazing. I would guess that's where most of their business comes from. Anyhow, even if you call Audio Classics just to get a second opinion it's worth it. Very nice group of Mac lovers. The amps are repaired by ex McIntosh engineers from what they told me.
