I am running cables for the 2KV and 500V TBW Power Supplies and I was looking for a way to provide a strain relief for a Millen HV connector with parts on hand.

I found using the soft outer plastic shell from an old microphone connector works great. The electrical tape securely holds the shell to the HV connector while allowing the shell / connector to rotate freely around the HV cable.
