Re: design for new capacitor

Hi Dr.,

been there, done that, when a newbie coiler. See:

http://home.datacomm.ch/k.schraner/pcb_cap.htm

...cannot recommend it without reserve: lots of work; not very long 
live, because of the corona problems (as mentioned by Gary Lau). An 
MMC is the much easier, more reliable way to go. If you really do it, 
never try the cap out without having it immersed in oil. If I'd have 
to do it again, I'd change and simplify the design a little. It might 
then become some more reliable too, if avoiding the beginner's 
mistakes. Can create and send you an off-list sketch, of what I mean, 
if you like.

Regards,
         Kurt
