Ok, sorry to post this in a new thread when I have another active on here, but the nature of the request has changed.
In case it's helpful, my original thread was here: http://audiokarma.org/forums/index.php?threads/next-steps-after-sony-str-6800-sd-re-cap.844366/
Before, I had completed a re-cap on this amplifier and thought things were fine. Well, since I found myself with some time off, I decided to bring the amp home (it's intended as an office setup) to really push it and see how it sounded at higher volume.
At first, all was well, but now, even at low volumes, it fluctuates from playing normally (and beautifully) to either the left or right channel fizzing and cutting out before cutting back in. The relay isn't kicking on, connections seem solid and no amount of playing with them seems to make a difference, the cutouts are seemingly random (i.e. not particular to louder musical passages - and I've noted this on classical recordings, so I'm not slamming it with metal or anything). Likewise, I don't think the problem is dirty contacts in the knobs or anything as fussing with those doesn't address the problem.
I'm half wondering if this had been going on at the office for a while or if this is new occurrence, but the bottom line is that I need to figure out what is causing this and fix it. Can anyone point me in the right direction as to where to troubleshoot this guy? Given my druthers, I'd love to keep it in service, but it's not much use to me while playing the "channel cut-out lotto."
Thoughts?
