Hi
I'm tearing my hair out trying to find some replacement capacitors. They're 3300uF/50V, 6800uF/16V and 4700uF/16V but they're all 10mm pitch leads. I've tried RS, Farnell, Rapid, even bloody Maplin. Farnell have them, but US stock - £16 charge for a fiver's worth of parts. Hmmm.
Digikey and Mouser have them as well, but they have £12 delivery too.
Am I missing an obvious supplier, or am I just going to have to bite the bullet?
Cheers

Just get them with axial leads and bend the lead round to suit. Use some heat shrink or spaghetti tubing for insulation if necessary. Is space so tight that you can't improvise?
-
It's silly, but have you checked the PCB? maybe it has extra holes for other sized capacitor spacing like they quite often do.
-
Slide on a short length of sleeving on the lead you bend around the body and make it fit. Glue it down with either thick superglue ( one big drop under the body) or stick it down with acetoxy free silicone sealer. If you are lucky you can drill 2 2mm holes in the board and tie it down with lacing twine. I still have a roll or two of it around, makes a nice strong mount.

What are the caps for? Wouldn't recommend axial lead caps if it's low ESR, as I've never seen axial lead low-ESR caps.
-
They're power supply smoothing caps. I'm reluctant to do a bodge-up, just because it's a really nice piece of equipment. I've got it apart to replace a Rifa X capacitor which looks a bit shady, and I just thought I'd replace the power supply caps while it was in bits - they're 20 odd years old.

Rapid have 10mm pitch snap in types - could you use those?

Really hate Samwha caps... Pulled about 30 of the buggers from LCD and plasma TVs... they don't last. Plus Samwha's HE series is unsuitable for PSU caps being a non low-ESR cap. You really need to use low-ESR caps or you will either have a non functional device or one you need to open in a few years to repair again.

CPC have a range of Panasonic caps in 10mm pitch. They have 3300uF/63V, 4700uF/35V and 6800uF/35V.

you could try ebay but then heaven knows where some sellers get their stock from.
