Do you know what run # your chassis is? https://philcoradio.com/repairbench/tips/svctip35.htm
It took me a while to find what you were basing updates/modification on as I didn't show up in any Philco tech guides or service bulletins. Looks like that update is runs 15 and higher. I only place I saw it was in Riders. On my post #8 there's a link to SB 217B. <Service bulletin 217B says to remove resistors #17 (51k for BC and #18 (25k for SW) between the oscillator secondaries and tube cathode.> Did I miss that part? Didn't see it on my copy. How did 460kc alignment go?

I was down in the basement in my dad's

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
