I'm trying to get some wire and I found some that has this spec: M22759/11-24. I know that its some mil. spec and 24 AWG, but I have no idea what it means other than that and while I have tried to google the translation, I keep coming up empty. Does it have anything to do with purity? Thanks!

It's silver plated copper, mil-spec is good.

M22759 is a sort of gimpy way of abbreviating "MIL-W-22759", a government spec for PTFE-insulated silver-coated copper wire.

Technically, what you're looking at should be described as Mil-W-22759/11-24, which specified a 600VDC, 24AWG wire roughly .043in OD, including (PTFE) insulation, rated to 200 degrees C and composed of 19ea 36 AWG strands.

It has nothing to do with purity, no.

I am not familiar with the specification in question, but I am pretty sure the OD is not four thousandths of an inch - .043" perhaps?

Yep, one too many zeroes, doh.

Hmm, is it good enough to use as hook up wire in a β22? I get so confused about what to use after reading all the different things about purity and 5n stuff. I know what it means, I just don't know how relevant it really is.

Just don't get too obsessive about it. Some wires are nicer than others, but wire is wire.

Mil-spec SPC should be good for audio. If you want to be extra sure, you can grab some SPC from the popular ebay seller navships. It comes in all sizes and is priced extremely reasonably.

Then does solder type matter as much? I'm looking at 25 mil and 63/37. But should I get the Cardas quad eutectic instead? Does it really matter?

 

[Juaquin]

The Cardas is really nice stuff (I love it), but it's on the expensive side. Any eutectic is good, like 63/37 and 62/36/2. I believe Kester 63/37 is a preferred type around here.
