I'm repairing a receiver and among other things I have to replace some broken wire wraps.
The existing wires are too short for reuse and I can't find any 22 AWG solid conductor wire on the market specifically for wire wrapping, only 24 AWG and up.
Can I use regular hook-up wire with good results and if so what specific kind of wire should I look for? I would appreciate if anyone can give me some advice on this.
Making 22 ga wire wrap connections is not something I'd want to try (and I did wire-wrap for decades - still do, sometimes). As has been mentioned, you'd need a special bit for a wire wrap gun. But that's not the reason I'd avoid it. Wrapping solid 22 ga around a .025 square post will require a lot of torque to make the bends small enough. I'd worry about keeping the tool straight as the wrap process occurs.
Instead, I'd suggest you simply solder a piece of 22 ga hookup wire lengthwise on the pin, then slip a piece of heatshrink tubing over the joint and apply heat.
Do you actually have a tool for wrapping wires of that size? It's very specialized equipment that was used for mass manufacturing in a certain era, and without the correct tool, it's unlikely that you can produce wraps with the required tension for reliable connections.
Even with the correct tool, repairs might be "iffy" — it was really a one-time-use technology. Once a terminal has been wrapped and then unwrapped, the nice square edges required for a good, gas-tight connection are now somewhat blunted.
You should probably just use ordinary hookup wire to make repairs to that kind of equipment, and solder the connections. It won't be strictly "authentic", but at least it will be functional.
