[Steve Katz] Don't know about the 1kV rating, sounds pretty skinny.
But I've seen the blue corona (darkened room) around Millen HV sockets only
when improper mounting hardware was used or the socket installed with such
mounting force (stainless machine screws torqued to within a hair of
breaking) that the Millen socket material began cracking. When I install
the connectors myself, I've never had a problem. Same sockets and plugs
used on HT PSUs here since 1967-68 in many cases. Highest voltage on any of
them is 4400V, though. Never tried 6-7kV. Never used "tetrodes with
handles," either!
