I have a classic old sprague pure oil dielectric unit of .005ufd -at-10kvac
rating.  It is huge!  20" tall, 14" wide, 8" thick! (55lbs).  The plates
are quite rigid and held appart by tiny ceramic spacers.  The oil sloshes
around inside the unit.

	That's an interesting report.  I wonder if I slipped a
decimal point in my calculations here.  Should have mentioned that
oil contamination is a real problem (any time you get an arc in
the oil) and the things aren't really quite self-healing.  I
had wondered about using ceramic or glass spacers....

(Apart, not appart!)
