Thanks Bob, that really helps and it makes sense. That cap out of circuit has a dead short across it. What's becoming increasingly clear to me is that the parts layout I have for this radio is not correct. The #50 cap that is shown on my layout doesn't even exist in this radio and their reference to #59 as the AC line bypass cap is not right either.

I wonder if the reason for this discrepancy is because of the placement of the rectifier on the PT as opposed to the chassis next to the output tube.

Anyway, thanks again. Much appreciated.
