Greetings,
New member here.    

When I pulled the chassis all the resistors were changed out, and caps. The electrolytics and Bakelite block were not.  .

Schematic calls for 3 electrolytics (1 duel).  There were only two l electrolytics in place, lytic 61 was confirmed and swapped out. I'm confused on the duel electrolytic # 20 and 20a, schmatich doesn't show connections for 20a (?).

Welcome to the Phorum! Icon_wave

See https://philcoradio.com/library/download...20Book.pdf

20a is connected to one end of the field coil #59 and ground.
Cheers,
Bob
