UCC capacitors

Sunsun22 · 26th May 2008, 12:54 PM

I wish to purchase 8 UCC 68uF 63V (actual voltage is only 15V) capacitors to recap my Mark Levinson 38S. I saw them some months ago in Mouser but I cannot find them now. Is there any other places that I can find them?

Thank you

I do mean the type looks like aluminium cans, not those with plastic wraps.

doh, remove the plastic wrap, the can lives inside...

Changing my cloths will not make me a real king.

I am talking about the UCC 678D capacitors that the new UCC are LXY series only.

Is there anywhere I can purchase 678D now? 68uF 63V

Sorry man, misunderstanding... I think those are Sprague... tried google?

I seen on Digi-key plenty of these Chemi-cons, however:

...none of the "678D" series I never ever heard before about.

If you can stick with 68uF 63V LXY, then there ya go:
http://search.digikey.com/scripts/Dk...me=565-1857-ND
http://search.digikey.com/scripts/Dk...me=565-1858-ND

Are those used for voltage filering or audio transfer/decoupling?

For voltage filtering I would go into lower ESR ones, like Samxon GD/GC or Rubycon MBZ/MCZ ones. Panny FC/FM are also great choice and I would use 16V ones, if the highest spike on then is 15V (measure the spike with scope only, forget DMM) ...

For audio I would recommend true good audio caps, like at least Elna RFS or Rubycon Black Gate C series.
A 100uF 25V Elna RFS is available there:

...however it is a big suxxka, d12.5 ... will THAT fit in?

Thank you for the information. However, I am looking forward to recap the amp with the original caps, if possible.

I understand, but... what if they are nonexisting?

And what reasons to have - since they are very likely used just for voltage filtering - to stick with possibly fake caps that died already?

I could be wrong, but Chemi-con never produced a 678D type as far, as I know and I'm into the capacitor replacement bussinness for quite some time...

NCC LXZ, KY or KZE should be comparable to or better than the original LXY in all the relevant specs.
