Hi Brian and Merry Christmas,
Good practice would dictate that C-10 should be 50mf or less. If C-10 is a high value it can damage to cathode of the 35Z5 thru excessive current during warmup. R-11 helps limit the current. C-11 isn't critical, typically they are 30mf but you can go a bit large for better filtering like 47mf. C-12 is normally 10-20mf @ 20-35v. 100mf was probably meant for a portable set to filter the filament circuit. A bit overkill for the cathode bypass.
If you want to get something that looks somewhat correct https://www.tubesandmore.com/products/ca...0v-22-f25v or replacing them with single units.

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.

Now I think I've got!
