Still working on my Sylvania

Not sure about C1, C2 or C3. I see C155 - C158 on John's schematic. Looks like 155-157 are in one can and C158 is on it's own.

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.
