I used "magic" tape between layers, don't know if that is good or bad or how long it will hold up. I was going to soak the completed winding in varnish (did this back in 1976 when I rewound a power xformer for a AK 89) but decided against it. The #37 is so fine I was afraid if I broke a wire during final assembley (which I did) it would be dificult to fix. I have the OT mounted on the speaker now but have yet to try it with the radio.
