I found out that Silent Hektik recommends even higher ... 33,000 uf? My capacitor is “beefier” than the original at a 50v rating, but still 22,000 uf. There may be some potential benefit to a higher micro farad rating, with no real downside. It’s still unclear to me what the capacitor actually does in this circuit. I’ve read some descriptions of that which are obviously incorrect. When I take the time to find out for sure I’ll post it on this forum. Of course there are people participating here who can probably tell all of us the real facts already.
