Some 8 years ago or so, I bought a vintage C22 McIntosh preamp. The ad said "professionally serviced."
I'd prefer to service it myself, but that was what was available, and then, OK, one job less. After all, I did not specialize in Macs. 

I did call the shop (they gave name in the ad) at some point, to ask some questions. They indeed existed.

So. I do not use it a lot, just occasionally. Recently I was listening to it, after having bought some new CDs, and the Tape Monitor switch dropped one channel. I wiggled it, it worked, and I decided it was time to use some Deoxit, for which today I opened the amp.

When I bought it, they did show some pictures that showed new caps (one being CE Manufacturing).
But today I saw some caps, the pics of which I have attached, that I do not think are new replacements.


So, I did spray some D5 inside the rocker switches, and am planning to replace the rest of the electrolytics.
