The tangs are the common lead for the capacitor not necessarily ground. According to John's schematic they are connected to the -135V bus. That's why those caps are mounted on insulating wafers rather than directly to the chassis.

I think you'd have an easier time leaving the old caps in place and leave the leads going to the tangs. Clip the wires going to the + lugs for each cap section and solder them to you new caps. Solder the negative leads of the new caps to the old tangs.

At least until the set is working - then maybe go back and re-stuff them if you want to.

C158 is in the same can as C178, C210, C181. How's that for confusing. Sylvania never seemed to like C1A,B,C,D You need to look at the part list to figure out which ones are in which can.
