When you talk about the terminal strip of the bake lite capacitors, you're talking about C100 and C101?
Did you change those?
I got safety capacitors years ago but never did the change. It is deamed much safer and up to code to use that instead of 1940s line filter caps...
I really should get to it.
I was reading my notes on the transformer from when I worked on the radio years ago (the threads are still on the phorums) and after a 8h radio session it was warm to the touch, not hot to the touch and far from burning.
On this topic at that time it was mentionned that some bad tubes or caps could draw enough to get the transformer warmer but the situation wasn't worrying. It was mentionned that variacs or bucking transformers was the way to reduce voltage if we tought it was needed.
As far as I understand, electricity in late 1940 was at 117V compared to the 125V I currently have here near Montreal. maybe the issue isn't as big as what you have. I wonder if electricity was the same back then north and south of the border, and if Philco Canada had different values to account for that?
I'll do more monitoring on mine soon with heat in mind.
