New to me Pf-50t. The right side transformer (looking from the front) gets hot to the touch after a couple hours of light/medium rehearsal. Not burning hot, just a little too hot to hold with my overworked, calloused, tradesman's hands. The left one stays room temperature cool. I just bought this amp used but it doesn't have a scratch or dent on it. Sounds fine at low/medium volumes. Does the design call for one to work harder than the other. Seems like a dumb question I guess. What am I missing? Need help, wanting to gig this amp Tuesday night.
