high Quality capacitors

[roger smith x294]

Preben,

Thanks for your comments on DCS caps.  I never tested mica caps having seen a
table showing DA = 1% for mica compared to 0.02% for polystyrene.  This is yet
another example of the chaotic results reported.  

I don't know "Suflex" ...can you provide an address (prefereably in the USA,
since our purchasing staff are skeptical about the existence other countries!
#@$@!%! )

I would probably be quite satisfied with the polystyrene cap you quote.
It is very small physically.  What was its value?  Do Suflex make them in
500 pF or thereabouts?
