Also to Craig: Is your yellow tape thinner, thicker, or the same as 3M Scotch "Magic" tape which is polypropylene and what I used in my 453.

Craig, how did you handle the ends? When I did my 453, I painted a trace of corona dope at each end after each layer.

I did exactly that (wind and retrace) with the 576 transformer rewind. That has a whole lot more
turns - 1400 of 40 gauge - and I levelled each layer with yellow transformer tape, which is nice and
thin. Impregnated with wax, and it continues to work like a champ.
