48-1286 Distortion after warmup
#1

My 48-86 sounds great when I turn it on, but I noticed that after about 15 minutes or so it starts to sound distorted. This isn't caused by drift, as tweaking the tuning knob can't get rid of it. Any guesses as to which part could be causing distortion after warmup?
