I bought my first D-1200 in 1986, it had a few cold solder joints within the first year... common problem with mid 80's stuff. Only issue I've ever had and it's been used daily.
I picked up another of these in 2009 and now run them as mono blocks. (look for the units with the bridging switch on the rear). I also replaced the meter lamps with LED's... I love these amps!

I am not qualified to really review it, but am super pleased.
I bought a bunch of stereo equipment at a yard sale yesterday for $25.00. Guess what was in with it? Yup, a D1200. I didn't know the name Proton until I looked it up online. But I read up on it, found this site, cleaned it up, and it functions fantastically with the exception of fuse lamps.
I am running the Sony STR-DA30ES receiver (that was part of the yard sale stuff) as a preamp and then to the Proton. My old 2 channel Pioneer speakers have never sounded more clean, crisp, and smooth. And I am not even pushing the D1200, running it around 40-50% of the dial before I am afraid of toasting the speakers or bouncing the family pictures off of the walls. It caused the cd player to skip multiple times.
And there was other nice stuff there from Sony and Denon - guess they just didn't care anymore about it.
