If you have an old lap steel, PA amp, or amateur radio transmitter, you might be familiar with the screw-on Amphenol microphone connectors - the ones with one connector in the center.
The Amphenol series for these are 75-MC (with an M or F suffix for male or female), also numbered 8075-MC. Switchcraft made them too - they'd be a 2501F or 2501M.
At any rate, millions of these things were made and are still in circulation. I have a handful which I use to make up cables with the Amphenol plug on one end and a 1/4 phone jack on the other. Some folks will convert their instrument or gear to a 'modern' jack, but there are enough of these connectors still around that we can make up a proper cable instead.
Here's how we make one up. I like working with these connectors - they're easy to assemble and they're super reliable.
Easy to take apart. Step one is to remove the screw on the shell.
Note how the shield on the cable was soldered to the spring.
We're going to solder our new coax shield to the spring, so cleaning it up will made soldering easier.
That piece of cable jacket looks like some kind of pasta shape - maybe it's Cavolini No. 2 or something. (Cavo = cable in Italian).
This is Canare GS-6 cable, by the way. Great stuff.
The shield will have to be trimmed back - this is a bit long.
Don't use a lot of solder - if it's too thick it will be hard or impossible to fit into the body of the connector.
Then trim the center insulation to expose the center lead. Sorry, I didn't get a picture of that. Easy to figure that out.
Then solder it in place.
How easy is this?
The whole thing is quite rugged and will resist having the cable pull out of the connector.
The built-in spring strain relief is a great touch.
Really a clever design, don't you think?
The whole cable is about 10 feet in length.
I forgot to get a shot of the whole thing - it took like 10 minutes to do this so I was just working away and forgetting to take pictures of everything.
You can probably visualize a red 10 foot long cable with an Amphenol connector on one end an a phone plug on the other! :-)
Works perfectly. This one is going off to a lap steel player in Florida. Another vintage lap steel back in service with the proper connector.
