[sdiy] NPO caps in P08 and Andromeda

[dragons]

Hi,
well I worked on a Jen SX 1000  two or three years ago.
and on the list of mods I found on the web, ( which the owner wanted ) 
was to change the filter caps from ceramic to silver mica. ( or was it 
polyester ? )
I wasn't sure it would make much difference, but it made a great 
difference. I would never recommend using ceramic caps in filters.
regards Peter
