Hi Richard,
I thought you'd have opened a real discussion here, but haven't seen
anything yet. So, here's my thoughts -- I've done a lot of SP-600's,
and they each have in the neighborhood of 55 BBOD's in them. I've
usually used disc ceramics in most places, with electrolytics where
needed due to value, and poly's for the few interstage coupling
applications, particularly when RF is involved.

I have seen a lot of rhetoric about how bad the Sprague Black Beauties
are and they should all be replaced, but nobody indicates a reasonable
replacement. I have some 0.22 uFd BB's that I am thinking of replacing
with polypropylene film non-polar caps. Is this a reasonable choice? I
assume non-polar caps can be used just like polarized caps for DC power
filters. Does one just pick a positive terminal and go from there? Other
options are ceramic disk or electrolytic. What is the recommended
replacement? Please advise.
Richard
