Caps for JR's QS&D isolating powerconditioner

Posted by pmkap (M) on July 28, 2005 at 07:30:34

After much effort and aid from other tweakers, I've found what IMO is an excellent complement of caps for the Jon Risch QS & D powerconditioner. Solen (SCR, Axon) metalized polypropolene for the cap accross the secondaries. These have bested various polyprop in oil motor run caps, GE, ASC, Aerovox, etc...., and are reasonably priced.
As the voltage accross these caps is rather low, 15-50vAC, voltage ratings of the caps is not a major concern, within rational limits.

For bypass of the Solens, and Auricap .47uf has proven to make the excellent even better. I realize Jon advocates a .1uf for bypass, but the larger Auricap appears ideal for a single bypass cap. And additional bypass in the form of .1 and .01 Auricaps, provide incremental benefits, though it does get substantially more expensive.

I'd appreciate comments and suggestions from those with actual experience with this project.
