Hi all, Me again.
I've been replacing all the caps and came across a problem with the electrolytic capacitors that I'm hoping someone will help me out with. It's obvious that there has been a repair and replacement made in the past as two of the wires leading from the capacitor can have been cut and a large cardboard capacitor added to the underside of the chassis. I'm not sure where to begin to describe the issue I have but maybe just a simple answer about what I should be seeing based on the schematic will clear things up for me.

Cap 21B appears to be the one that was replaced. This large cardboard cap has a wire coming out of it that leads to a terminal which is mated to the speaker field coil (76) while the other wire exiting the cap leads to the terminal between the two large resistors on my new Candohm resistor. Cap 21a Looks to still be inside the original can, it has a red wire that comes out of the can and goes to the field coil (and a bunch of resistors) but there is no wire that comes out of the can that leads to my candohm resistor between the 28 and 26 ohm section. Since there was only two wires cut from the original capacitor can which I'm thinking was for 21B, was there never a wire that went to the candohm? The green wire and Black wire seem to be going to the proper places, I'm just not sure what I'm supposed to be seeing here.
Also, based on the schematic above of the Electrolytic capacitor does the little black box represent the positive side?
I guess I was also confused because I always thought the negative side just went to a ground on the chassis.
Any help would be greatly appreciated.
EDIT-- Wait a minute, I think I just figured something out here when reviewing my post, is the Candohm resistor considered a ground because the last 26ohm resistor is connected to a ground? - I told you I was new to this right!?!
