Hi
Alden and LEMO make some nice high voltage connectors.
I have used the Alden plug in connector from Surplus Sales. They are $15
for a set, plug and socket. 15KV rating.
Alden are now owned by Amphenol.
I have seen Lemo HV connectors on EBAY. I have a bought a few for my new amp
projects. Farnell I think sells them as well, however the prices are crazy.

Many people dont know what LEMO connectors are so nobody bids on them.
