I've had an old (no functional) Amber monitor laying down in my basement for quite some time so I decided to tear it apart last weekend.
There were 4 coils around the picture tube. 2 inner coils, and 2 outer coils. All were made with stranded magnet wire. The inner coils had a relatively tight twist in the strands while the outer ones were essentially not twisted.
The coils came out cleanly, although I am concerned that unwrapping them could damage the insulation.
But.. the question.
Would there be any cost/benefit changes by using fine stranded magnet wire in the coils? Presumably one would effectively have 10 times as many turns, all wired in parallel by design.
Any ideas for the Tube? I'm still wondering if they Implode
