I’m working on a Philco 630 that has had some restoration work done prior which is confusing me. Both of the two original electrolytics were still hooked up. I replaced the 16 mfd one already.

The photo is the 8/8/10 electrolytic. I’m not sure how to safely wire the positive and negative connections. I’m assuming the blue circled wire is the common negative because it goes to the center tap but I don’t know how to tell from the three, red, black and silver connections which one is the 8, 8, and 10 connections. There isn’t anything marked on the cylinder to indicate which is which.

I realize that I should be able to find this out from the schematic but I’m new to radio restoration and I just don’t want to mess the polarity.

The yellow circled item at the bottom is a 20 mfd cap that I don’t know how it fits into the scheme. It goes from the speaker connection to Pin 1 of the 4989 Bakelite condenser. Not sure why it’s there. Do I just remove it after replacing the electrolytic I’m inquiring about?

Any and all advice is more then welcome.
