  Thanks for the reply although if I read it right they would need
plates out as well , I am running a home made mosfet amp around a 900w
max input > drive dependent  so arcing is likely

  but perhaps a local cap or supplier will be offered ?

  Simple and affordable incidently

  I fiddled with this  http://www.w6kan.com/ssamp.html
  for a while then bought a kit from the states (based on it) and
assembled it
  I had happily ex pmg transfrmers for the 50v supply ( you know ohms
law) and some 100v caps for huge filter  from some 5kw ups's the rest
was pure $ and time
  Now do you have a spare air cap ?
