Hi Popper, I bought one of those AR amps new, way back when. It sounded okay, as I recall, though my system at that time wasn't as high resolution as it is today. It did, however, blow up on me for no apparent reason. AR rebuilt it at no charge and I sold it to a friend because I liked my Dynaco 120 a bit better. A couple of months later the amp blew up on my friend and AR had to repair it once more. So my sample appeared to be unstable, but I don't know if it was representative of typical production. This is one of the only amps I've owned that failed in service.
