Can't really tell what connected to what but looks like the 2 16 mf caps connected to the filament of the 80 tube. The other end is connected the B- or the hv center tap. Also looks like 47 got a little hot and bothered. This could be from having 32mfd rather than 8mf
.
By adding 24mf to the input capacitor there is a good likelihood that the hv would increase and cause more current flow thru 47. 8mf aren't a common value any more but 10's are. Those are fine. There's also a temp rating typically 85 and 105 deg. 105 are the preferred.
There are also film capacitors in the mf range. Last forever, physically large, and a bit more pricey. Generally most folks go for the electrolytic.
Some guy do this when replacing the electrolytic. https://www.philcorepairbench.com/rebuil...trolytics/

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!
