This message was posted a while ago by Bob <misiura-at-nccoast-dot-net>, and it
looks like it might have the answer to your problem. The units from Hosfelt
could be used to make a 30kV MMC system with either 10nF for $19.90 (using
10 .1uF/3kV) or 22nF for $26.25 (using 15 .33uF/2kV units, this is what I'm
planning to build).
