Don loads of cable soldering in the past ... but prepping the ends on
this cable is proving difficult

It's tinsel wire and is very difficult to deal with.
What I do is to try to tin it with the iron anf hopefully melt the
insulation, then find the finest strand of copper wire you can get your
hands on and wind it around the end then apply a little mote solder on
order to make a sort of bootlace ferrule.


+1, although I have also sometimes used a tiny gas torch as another
poster suggested. Another technique which used to be used on Litz wire
was dipping the end in meths and setting light to it, followed by gentle
scraping (but that was an enamel, not a fibrous insulation)

Oh, I remember that. Winding IF transformers...
