Re: MHV and SHV connectors.
I purchase quite a few connectors through Newark which is also called
Farnell. Just got a bag of Amphenol MHV sent in. You can find them on
line also. I prefer to use their older (pre-Farnell merger) short fat
catalog, but a phone call can request the un-wieldy over weight phone
book size catalog.
I also purchase HV wire from Newark, rated to 10KV, quality stuff from
Belden and other mfgrs.

What do you like for HV connectors these days? The old Millen connectors
seem to be hard to find, and I don't consider them safe for use except
inside an enclosure. I will need to run HV (ca 3 KV) from one cabinet to
another and would like to make a good choice. "Good" means safe and
cheap.
Next best is safe and uncheap.
What I'm thinking of is is something with recessed contacts so that
accidental contact with an energized connector would not likely result in
shock. Yes, of course, any energized HV connector is dangerous when
disconnected but I want the laws of probability in my favor. (I
absolutely
cringe when I look at the picture of the 3.5 kV supply in the `91 ARRL
handbook. Two open Millen sockets on the front panel of a cabinet sitting
on the floor right at kitty-cat-nose height.)
MHV are suggested in some ARRL designs, but I don't find current
information on them which makes me wonder if they're going obsolete. SHV
appear to still be made but are more expensive. Both of these are
coaxial,
which is unnecessary although it does provide a convenient geometry for
the
recessed contacts. So what do you like?
Thanks & 73 from the new Carl on the block, WS7L.
