New Old Stock large screw connector. Perfect for use with vintage Heathkit , Eico and other test equipment. Also used with vintage guitars, guitar amplifiers, Ham radio gear and other collectible equipment. 

For instance, they were used on 1940's Regal, Kay and National electric guitars and harp mics like those made by Turner, Electro-Voice, Astatic, Shure, as well as 1940's tube amps like Masco and Oahu.

This listing is for one (1) connector. I also sell lots of four (4) units of these at a discount in my eBay store.

These Amphenol 75-MC1F Switchcraft 2501F equivalent screw-type connectors are becoming difficult-to-find. 

Buy with confidence from a top-rated, experienced eBay seller and hobbyist.
