Filmlytic Capacitor

Stumbled across this in my search for The Perfect Capacitor:

Dearborne Electronics Filmlytic Capacitor

Not only do these capacitors seem compact, they are available in a voltage range from 600 VDC to 1800 VDC (transmitter tube buffs take note!). Capacitance ranges are 200-400uF for the 600V variety, to 18-42uF for the 1800V variety. Largest case height is about 5 inches. Dielectric is probably metallised polysomething.

I believe Michael Percy sells them:

I found some 100 uF @ 2200V film/oil? caps with
very low DA, at a local electronics shop. Surplus stock
originally intended for a defibrillator. I used three
on an unfinished tube amp chassis (ran out of
budget before I could buy the output transformers).

Mine are unvented, and thus may not be all that
safe to use on a continuous basis, even highly
derated (550VDC max)
