Hi and welcome,
Typically with bad filter caps you'll hear 60cy hum and diminish volume/distortion do to the caps turning into resistors pulling the hv down. The opt pri should read in the 100's of ohms not the 1000's. I'd say it's bad. It's not uncommon to find an open pri on the '40s Philco sets. Replacement wise your looking for something with a 12K ct plate load to 2 ohm spk or so. Wattage is fairly low as the hv is low too maybe 2 or 3 watts. https://www.radiodaze.com/push-pull-outp...em-hx125c/ It's a little overkill. Cost isn't much more. GL

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
