'Oversized XLR'

[mjrippe]

I don't think they are still made, so you pretty much have to buy an old stock connector. Try Leeds Radio here in Brooklyn.

That's an EP-3M connector. They certainly still make and use EP-4, EP-6 and EP-8 for PA speaker connectors. Like this:Amphenol, XLR, Connector, Audio

Excellent! Thank you!

They were very popular in the earlier days of broadcasting. You would see nothing but P boxes on the studio walls and on the ends of microphone cables. I still have a bunch of the male and female P connectors.

So now I'm thinking my best bet to keep things stock would be to build an EP-3F to regular XLR Male mini-cable.

Thanks for all the input and information.

I believe the mics originally shipped with no connector at all, so stock isn't a question.

I'd change it to XLR, as using a P adapter adds another piece of contact resistance on a low level chain, with an aged P connector likely having less than stellar contact performance. If it were a higher level connection, I might not worry about it.

Absolutely agree with Mr. Williams. Adding another connector, and especially an old cruddy noise-prone antique is just asking for trouble for no useful purpose. Chop it off and sent it to a museum where it belongs.

Good points...maybe i will chop it off. Maybe do a new cable. I've never opened a mic up to redo anything so this might be a good learning experience. Any suggestions on how to handle strain relief?

It looks easy enough to open up. Just duplicate whatever strain-relief is already there.
There are good photos and manual pages here: RCA Type BK-5A and BK-5B
