Dan,

I’m talking about extremely thin wires: 22-24 Ga, or less.

There’s a cellophane or plastic coating on them which makes soldering impossible unless it’s removed. There’s also a nylon core, but that can easily be removed with scissors.

I can strip wire with the best of them, but this had me stumped until I thought of the Jasco.

Those methods are great for thin wires but I was referring to the extremely thin insulation on say, stereo headphone jacks. You know, when the jack breaks and you have to buy a plug and solder another jack on?

Each wire has two leads, one bare copper and the other a very thin wire coated with cellophane or something. You have to strip that insulation off before soldering the common (thin) wires, and then the mains to both left and right sides of the jack.

Well, I figgered it out! Jasco! Don’t know if they even sell the stuff any more, but I found some buried in the basement. Methylene chloride is the active ingredient and dissolves the insulation while leaving the copper alone.

I also suspect brake cleaner might also work, but mine had evaporated.

So anyway, in case you’re interested…

Now to figure out which lead is right and which is left. One is green, the other red.
