"...if you decide to use the JJ cap, note that it has four capacitor sections: 40uf, 20uf, 20uf, and 20uf, all at 500v, right?
You need three high-voltage caps, with the original being specified as 40uf 450v, 30uf 350v, 15uf 350v.
There is also a 50uf 25v cap specified on the schematic and parts list - that could be replaced with the Nichicon 47uf 100v mentioned above (from your kit).
So my recommendation would be to use your new JJ cap in the following way to best meet the need: wire up two of the 20uf sections in parallel.
This will make your JJ cap have 40uf at 500v (to replace C52A, 40uf 450v on the schematic in the parts list), 20+20 = 40uf at 500v (to replace C52B, 30uf at 350v on the schematic in the parts list), and 20uf at 500v (to replace C52C, 15uf at 350v on the schematic in the parts list). This will meet or exceed all of the specs of the original power supply filter caps in the can. Finally, to replace C52D from the parts list, you can use that small Nichicon 47uf 100v, that came in your kit. That can be handled separately; we can come back to it later.
There are other ways to proceed, but this is my advice right now anyway."
Here is the same recommendation again, in list form:
C52A was originally in the parts list as 40uf 450v --> replace it with 40uf 500v in the JJ can
C52B was originally in the parts list as 30uf at 350v --> replace it with 20+20 wired parallel for 40uf at 500v in the JJ can
C52C was originally in the parts list as 15uf at 350v --> replace it with 20uf in the JJ can
C52D was originally in the parts list as 50uf at 50v --> replace it with that small Nichicon from your kit, 47uf at 100v
If you choose to follow this advice of wiring two of the 20uf can cap sections in parallel, let us know. We'll tell you how when it arrives and you tell us the letter codes on the terminals. It only requires a wire connection in the right place.
