content: The cables for a microphone and mono speaker, one for each. The speaker's 300ohm. I need only 10'.The center wire is multiple strands.

content: "Single strand""multiple strands"Which is it..?You seem to describe coax. Is coax not good enough?Tim

content: There's a center wire that has multiple strands, that wire is insulated.Around that insulation is a braided cable (the shielding).Finally there's insulation around the whole thing.Yep, it's coaxial but I've not seen any like this. I guess I've looked in all the wrong places.I'll have to check the places I haven't yet. I am also going to tear apart some cables with RCA jacks on them to see if they'll do. I probably won't find an exact replacement.

content: I have some. It's labelled "High quality screened 1 core audio cable" Very flexible. The fact the it says high quality probably means the opposite. Got it from an electronics shop with a sort of professional-sound-guy feel to it, like DJs or karaoke hosts. Nothing particularly high end. Try googling for that?

content: Sounds like guitar lead cable.It should be pretty easy to get from music intrument places, ranging from generic stuff like this (http://www.swamp.net.au/swamp-sgc-103-pro-line-instrument-cable-per-meter.html), to name brand stuff like this (http://www.swamp.net.au/canare-gs-6-mono-instrument-guitar-cable-per-metre.html).

content: Ok, I'll follow on those ideas and links, meantime here's a measurement for the conductor. The question is what gauge is this? I guesstimate that it's from 18-24AWG. If I measure only the wire, it's 0.02" or 24AWG or if we measure the jacket too, then it's 0.03" or 0.04", do we measure from center-mark to center-mark on the ruler?i.e. is it 0.04" or 0.03"I counted ~40 strands in the conductor. I'll be fine with anything with 10-15% of that.
