Mike, this is the most definitive explanation that I have received. I am
sure that other will agree with you and so I am posting your post to the
entire group. I never thought that the mica connector was for RF. It was
this type that broke down in every instance with about 2,000 volts or more
when modulation voltage was applied.
Thanks

I have a Millen ad in a 1963 CQ Magazine that says the Red and Black Millen
connectors are for HV and the Brown (yellow) is a special filled bakelite
for RF use ONLY! My friend says the Reds are the best since the Black are
pigmented with carbon to give the black color. Sounds right. Mounted on a
plastic disk they do count as pretty good. Metal screws are asking for
trouble. Nylon handy for this. 73 Mike.

Unfortunately Ed these are the 'Millen' connectors are only good to about
2KV. I know the spec say more but this was discussed at length on the
AMPS
reflector. I have a bunch of the brown ones where the flanges apparently
broke down under HV stress. I couldn't prove it but the insides of the
material looked to have been molten.

I got my high voltage connectors from RF PARTS [EMAIL PROTECTED]
part # 37001 (A,B,C,D) rated for 7000 VDC @ 2 amps. Chassis mount flang
$6.90, cable mount shell $5.90. Good luck.
