Hi Everyone,
I'm working on an SA-7100 and was contemplating replacing the filter caps. I know the big sized ones are getting harder and harder to find all the time. I started looking through the forums and ran across this post:
http://www.audiokarma.org/forums/index.php?threads/my-sa-7100-drops-in-and-out-of-protection.497819/
where the OP followed patfont's thread: http://www.audiokarma.org/forums/showthread.php?t=503150
in using Panasonic THA caps. (Patfont used them since they laying around)
In general I know that high ripple current rating and low ESR are the things to go for, but looking at Nichicon caps at least, I can't get a feel for which series (e.g LGU, LGY, KG, etc) have the better specs. LGU's seem affordable and will fit.
The same Panasonic THA is still available, but is a bit more pricey than the Nichicons.
I wasn't sure if there were better options in that class.
Finally, I was wondering if someone had links with pictures on how to best reconnect the wiring the snap-in type terminals. On the SA-7100 the connections to the filter caps are wire-wrap. In the first thread I mentioned I think the OP did a regular soldering connection. I've seen a few posts were Mark The Fixer mentions using "Experimenter's board", and Patfont in his post did something cool with what I believe are crimp connectors. I've also seen a few posts where people "re-stuff" the cans, although that wouldn't help too much since I can't duplicate the wire wraps, and I don't think the old caps are that huge. Any visual guides out there that someone could point me to?
Thanks again!
