Commercial caps / MMC

  Hi all,

 Yup, more from the peanut gallery.  This time, it's *que dramatic music*
Commercial cap vs MMC

    Why do commercial caps reportedly give better performance than an MMC?
Aren't they both an extended foil design?  Is it the inductance of the
wiring in the MMC?  The caps themselves?  I made my strings, and last night
secured them in parallel to copper-clad PCBs, so I have a block of caps (7
strings of 11 in a 4x5x12 or so block). DC test charge-discharge worked
beautiful, and it looks nice too :)   Hopefully lowered the inductance a
bit, and gave them a lot more conducting area.

  I know that for small coils, MMC's rock.  They beat out commercial caps by
being "buildable", series/parallel them till you get what you want.  You can
add and remove capacitance in small amounts to test/tune, replace a failed
string or individual cap, and not weep ower a blown commercial cap from
overvoltage. You all *are* using saftey gaps, right? *right!?!*  :)  I have
to admit, I'd be a lot less scared of blowing an MMC than a commercial cap.



    What are the specs on the Hosfelt caps being used, and the price each?
Maybe they can be ganged up on a pole-pig?
