RE: High Reliability - DRSSTC II - Proven

Actually not.  Ventilation was extremely good and not a scent of ozone.
It was in a rather large (very high ceilings)
manufacturing area.

I had about three strike targets set up at about 45" to 60".
The picture below is from that demo (it was taken by the staff
photographer here so it didn't come out to
good)

The 42L capacitors i'm using are 2000V versions.  I'm not sure what the
internal make-up of them is, but
they just get slightly warm during long operation.

We had a professional videographer come in to record the demo (with me
presenting), if i get the tape i'll
try to get that put here on the web.
