It could be a bad solderjoint or hairline crack across a track. Maybe it is a faulty IC itself? If you don't have a scope or ESR meter, maybe you could try replacing all of the electrolytics around all of the IC's? Or go over all of the solderjoints with your iron. Replace all of the electrolytics around the verticle output IC heatsink. If one is right next to or inside of the heatsink mount it underneath the board if you have room. If the front panel buttons plug into the main board, unplug them, lubricate the pins and re-insert the plug.
