Hi Electronic M.
I see what you mean about the Resistor soldered/grounded to the chassis. On one of the lugs of the electrolytic before i had taken it out there was a resistor connected to it, with an additional yellow wire trailing off onto one of the vacuum tubes. It could probably be assumed that is what you meant for the 22uf capacitor. I'll see if i can show ya some photos just before i get into any soldering just to be sure!
I had posted on RonL's post in hopes to find a schematic(obviously in his own time).
The old capacitor is literal mush and liquid so it wouldn't work out to test it...
Anyways here's a bunch of pictures.

That resistor goes between the chassis ground and the silver lug which is also connected to a yellow wire, there is a purple wire connected to the red lug going towards the left side of the chassis into what looks like a resistor and a round radical ceramic capacitor.
And the gold lug goes between that sand encased 2200ohm resistor that is 5 watts and connects to a vacuum tube, and another white/red wire that connects to a different vacuum tube...
I'll take more photos and draw out what i mean that'll hopefully explain it better then i seem to be able to ahaha
