[GreenKeys] Jack Selection for TTY equipment

[Sheldon Daitch]

Cory,

looking at some old documents that I brought back from my tour in Vietnam,
military tour, not tourism trip, I've scanned a few pages regarding the DC patch
panels used in the newer fixed station facilities built by Page Communications.

Looks like the patch panels used WECO 303A jacks for the looping circuits and
WECO 438C for the SET and LOOP jacks.

I will be sending the PDF separately to those who have posted in this thread.
27 pages with some repeats of information.

73

Evening Greenkeyers,

I wanted to solicit your advice with a project I have in mind. My current TTY arrangement Involves lots of exposed conductors, alligator clips and random wires. I'd like to tidy things up and build my loop supply into an enclosure with ammeter. Seeing as most of my equipment has quarter inch plugs, I'd like to build a series of jacks into the front of the unit to allow me to mix and match equipment. 

I'm wondering, are there certain types of jacks I should be on the lookout for? Won't the traditional style with nut bonded to sleeve create a shock hazard? Your thoughts?

Thanks, 
Cory
