I finally got the materials together to wind another transformer. This time I resorted to buying tape off Ebay since I was able to get it in 30mm width which was close to what I wanted. 1 1/4 inch would have been more ideal, but I think this will work. The winding resistances check out OK and there is tape between each winding layer this time. I did my best attempt at vacuum impregnating the assembled transformer with spar polyurethane. Just for fun I measured the inductance; primary is 7H and the overall secondary is 500H. Quite a bit of inductance there. I will put heat shrink on the secondary leads where they pass through a hole in the chassis. It's not the prettiest looking thing but hopefully it will work out OK this time.
