That oddball connector on old test equipment…
You know the one I’m talking about - this thing:
It’s a Switchcraft 2501f Microphone Connector. It found it’s way into low-frequency RF devices after WWII, where it remained until displaced by the superior BNC connector.
They’re still available, but they are not cheap - expect to pay $14-15 for a new one! If you’re not worried about looks, just replace it with a BNC and be done with it, you get access to a wider range of connections.
You can view the data sheet here, or order one from Mouser.com here.
