Tip is positive in all the Navy teletype patch panels. That's also how I have seen teletype line plugs wired. (polarity matters for a selector magnet driver or line relay)
I'd recommend adopting that.

I am changing it from the long frame style (TRS)

to the more typical plugs (TS).

In the past, I don’t think any of my equipment cared about polarity. But I’ve recently added a CV-2460 into the shack and it does care about polarity. Obviously, I can make the tip/sleeve whatever polarity I want. But I was curious what others do in their shacks. Do you make the tip positive? Would anyone care if the tip was negative? Any thoughts or opinions? Again, I don’t think it matters but just curious what you guys think.
