Anyone know the proper way to solder Litz wire (used in eg
quality headphones). My home-grown (but probably incorrect)
method is to strip the outer conductor, expose the strands to a
gas flame for fraction of a second to remove the varnish layer
(or whatever it is), use a clean cloth soaked in alcohol to
remove the soot (sometimes even very fine emery cloth!), and then
solder. Even this though sometimes fails when a substantial woven
cotton filler exists. Is there a "correct" or better way? Thanks

Our wiring shop, (mumble,mumble years ago), handled
Litz wire daily. The approved stripping method was a
meths lamp, then wipe away the carbon with isopropyl.
