Broken Mcintosh Meters

I used to own a MC2125 30 yrs ago, and the one thing that used to drive me nuts was the meters constantly dropping off sporadically. My dealer gave me a tip, but it didn't solve the problem permanently. If you take off the top, you'll notice there are vertical circuit boards right behind each meter. These boards are a plug-in type, and if you pull them out and re-insert them, this would cure the problem. I even tried a contact spray on the gold terminals, but occasionally the problem would occur. It seemed it was always the left channel, even tho the sound still worked on the left side. I finally sold the amp just because it frustrated me. And yes, I did make the new owner aware of the problem. You might give it a try. Or call, or email McIntosh and ask their opinion. And good luck!

For me it wouldn't be the factor of dumping amp that I like. There are amps without VU meters at all outthere.

Yup. Meters have mostly visual entertainment value. The novelty wears off after a while.
