Great! I'm glad to help get it working and share a little experiences I had over the years. We all had to start somewhere with someone who we willing teach us newbies a thing or two. I was lucky as it was my dad.
Hummmmm ? Well I'd try hooking an 20 to 40mfd @ 450V electrolytic cap from points C (going to the + side of the cap) and point D (going to the - side of the cap). Also having a good ground may help. A little bit of hum would be normal.
On your rf amp tube may just need to clean the socket. My model 70 chairside had a similar problem with the 27 the in the oscillator. It would play for a while then die. The filament would go out.
I was wondering if it had local/distance switch. The printed diagram I was using is kinda small. Now that you mention it I see it on the primary of the first if transformer. Haven't seen many Philcos with a L/D switch.

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!
