You could unhook one side of 59 so you don't have it ready blowup in your face at any moment while your troubleshooting. It may get you a little hum but not much most of the filtering is done by the other two caps.
Take a close look at both of the 6F6 socket between pins 2 and 3. What you are looking for are carbon traces. They look like black lines that are burned into the wafer material. If you see them, some sign of arcing I would replace the socket. Both pins 3 and 4 have hv on them but pin 2 is at gnd so 3 would be more likely to arc to it. Any black marks are over there worth have a look at.  Pinched speaker wires are common. They have hv too.
If not you may want to pull the 5y4 and watch the hv going to the plates. Just to be sure the transformer isn't bad. You'll want to watch it for 5 or 10min. Should be steady unless the washer or dryer are on.

Happy Hunting!

figure out what all those squiggly meant.
