It occurred to me that a particular technique for repairing open fine magnet wire deep within coil windings
may not be well known - I haven't yet seen it mentioned on the net. Maybe it's discussed out there somewhere
but I haven't come across it.
Recently I used this technique to fix the open primary of the T5 audio stage input transformer of the Hallicrafters SX-17
receiver :

I learned this technique decades ago from an obscure article written by an oldtimer, and have been successful with
it many times.
