I've got an x1 y2 cap to replace this, but now I'm wondering what is the best way to do this? Do I somehow remove this old one? It doesn't appear to be readily removable? How do I set up the new x1 y2 so that it's well mounted and safe from shorting against the chassis or whatever?

I would drill out the old one & put in a terminal strip
IF there is room. Alternate is cut the leads off ONE end of the
old cap. Use the other end for one end of the new cap then
make a "flying splice" for the other end.

BTW the resistor in your other pix went violently. Something
almost had to be shorted to do that......

It also looks like the wax cap just below the 470K resistor in this picture got a little toasted.

That blob looks like the line cap is soldered to the chassis.

You can cut it off and solder on a regular old fashioned
terminal strip.

Terminal strip sounds like the best choice in this case. And that pic was from before I recapped it, so ignore the wax cap. :)

Thanks guys!

Is that a single cap or a dual unit with a case grounded center tap? Have seen both types in that kind of strap mounted metal can...

You're right, it's a pair of line to ground caps. Somehow I didn't notice that on the schematics but I opened up the can and can see it has a 3rd tab inside which presses against the case. Thanks for asking that question.

This cap was far from dried out, BTW - quite saturated with dripping oily liquid!

Be careful, that oily liquid very well may contain PCBs....

Well, a little late to learn about that but thanks for the info anyway! I did wash my hands afterwards. :)
