Electrolytic capacitor replacement

Elegant would be more eloquent. Ditch the board. Hardwire direct. That's what I did. See the last couple pics on my system page.

Well played!

When I swapped in a monster film cap for the power supply electrolytic, I couldn’t fit the cover back on. Now I leave the cover off. Sounds better anyway with the metal gone.

pauly there a LOT of great electrolytics that are the same size.

Do you mean taller or wider. It is always per application but how many are there and what is it your recapping?

Vishay, Mallory, Cornell Dubilier, Panasonic, 25 more at least..

Radial right, not axial?

If the caps are snap in, then…..


Simple. Solder leads to the cap that are long enough for you to mount it at whatever angle etc… you need. Be sure to keep these lead outs as short as possible and place heat shrink over the lead outs between the cap and the board to prevent any possibility of a short.

The lead outs should be the proper gauge, solid core copper, to fit inside the solder pads. Usually 18 gauge is fine, but be sure. You can thin the lead outs before applying the heat shrink to prevent oxidation. Or use tinned copper, solid core conductors as used on most film caps.

If the cap fits over the solder pads with no need to angle, the lead outs will not allow you to seat the cap perfectly flush on the board. That’s ok, just use a product like Soundcoat vibration damping sheets, with adhesive on one side, cut a small piece or two to fit between the cap and board. It’s not conductive and adds that next level of OCD attention to the details 😊

Just saw this comment by you….

”I’m considering using a spacer between the pc board and the cap giving enough room for the leads to bend enough to fit the board. I have space on the board to fit a larger cap, but not enough to mount the caps on their side. The caps new will need to sit “upright”

This is fine. Use the suggested Soundcoat between the cap and board if you like.
