Proper Wire for Wire Wrapping

[DreadPirate]

I'm re-wrapping connections on a vintage Marantz receiver and notice the old wiring is silver coated copper. The pins are also tinned. So, do I need to use coated copper wire to do proper wire wrapping here or does any solid core copper wire good enough? 22 gage if that matters and I'm using a manual wrapping gun. I can't seem to find 22 gage wire that is silver coated...

Not of much help, but I did a lot of wire wrapping for many years 25 years ago.
As I recall the standard wire wrap wires we used (standard product at that time) was silver over copper, and bought in different length and colors.
It should be possible to still get it.
I know Farnell.com has it in 26AWG but only in length of 100 meters (app. 330 feet)

the oxidation over silver and the oxidation over solder are both quite soft.
Wire wrapping should be suitable for both finishes, silver plated and tinned.

The oxidation over copper can be very hard. I would not recommend plain copper for wirewrapping, just in case the copper oxide on the surface insulates the wire from the post at all those corners.

I've only been able to find 24awg silver coated wire for wrapping and it ain't cheap:

Would it make sense to use the plain copper wrapped and then finish off with solder? It feeds the output transistors in a 85watt amp.

Thanks Steve, I'll put an order together shortly.
