Okay, a couple corrections.

C1 D is in parallel with that resistor. It didn't register with me that that line is just a straight bridge to ground through the filter capacitor on the other end of the chassis.

The reproduction electrolytic can from Hayseed Hamfest used stranded wire that was too thick for the holes in the tub socket terminals. I ended up cutting half of the wires off to make it fit and feeding that through. In poking around tonight, I discovered that a single strand on the 60 uF section had separated from the rest and was hiding underneath, shorting that section to ground. I've removed that, but now I have to see what damage that caused.

I did try powering up since then, and it looks like the resistors are no longer overheating. I still plan to replace them, of course, but I'm now reasonably confident that that short was the source of my issue.

Basic symptom at the moment is I have faint hum through the speaker (not filter hum so much, more like volume up too high faint distortion) but no signal besides a faint chirping every once in awhile on all bands. So I'll have to figure that out. I plan to check my B+ voltage coming off the rectifier tomorrow (I think that's going to be 115VDC coming off of pin 8 on the 35Z5, but correct me if I'm wrong on that) and trace it up to the 50C5. It looks like it has to go through those resistors that were overheating, so I still have some hope that that's the source of my issue.

I'm still trying to wrap my head around the resistor pattern coming off of pin 8 on the 35Z5. It doesn't match what I'm understanding from looking at the chassis. Pin 8 has two resistors. One is definitely the 15K ohm going to Pin 1 on the 50C5 and connecting the the D section of C1. The other (the one that was burning hot) is connected to pin 8, but goes off to a terminal strip, hooks onto one of the 40 uF sections on the electrolytic can, and then runs through an additional resistor to the 60 uF section in the can mounted to another terminal on the strip. At least that's what I think is happening, I'll retrace it tomorrow to double check.

There's also some stuff wired to pin 1 of the 35Z5. I don't even see that pin listed on the schematic. I know it's factory, as far as I can tell the underside was untouched so there must be some reason, but I'm not seeing where all that is happening. Is Pin 1 on the 35Z5 a no connect internally? The metal is present but perhaps a look at the tube diagram will clear that up.

I'm just spitballing here. Hopefully some of this makes sense. I'm sure another glance over the layout will clear some of this up, but in the meantime any thoughts are appreciated.
