Two options, one try adjusting or replacing the pot on the bottom left side of the power board by the big set of caps, adjust the rails to about 193-195v.
If that doesn't work, you can get a new PS from sanway or get the one you have repaired. The one I got a hold of that died recently had a trace by the caps roast. Not a difficult fix, but hard to find without removing all the caps.[/QUOTE]
Thanks for the info. I tried adjusting the pot several months back. It went from power cycling rapidly without playing anything to smoothing out . Thought I had fixed it but as soon as it is pushed it goes back to cycling.
I'll see about a new power supply. Since my amp is older, would there be any advantage to a complete new amp (besides just being newer) over just replacing the power supply? Have there been any upgrades to the rest of the amp that I would be missing out on by just replacing the power supply?
