Also with the Millen connectors, those in the know mount them on a piece of insulating material with a larger hole in the metal chassis to provide better insulation. Mike

If you were to 'sing the praises' of those Millen HV connectors, which are advertised up to 7KV, Shane, WP2ASS, might bop you on the nose! I have used them to 2KV but I would go much above that because they lack a lot of protection where the wire goes into the connector itself. I have some SHV that require RG-58 or a reasonable facsimile thereof. Recently? I used these: One of the companies that makes a Megger uses it to 10KV. I'm only using it for 2KV but the bare conductor is buried deep inside the ABS probe so that it isn't exposed. The only issue I see is that the manufacturer doesn't state the current. It didn't bother me since I was looking at a max of about 300mA on my modulator. However, YMMV! Mod-U-Lator, Mike(y)/W3SLK -----Original Message-----
