Hi, having worked on a few tv's and monitors over the years, Corona dope
works, however each layer is awful thin. Its often the red stuff they use at
motor shops on windings as a finnish coat. Basically lacquer based as far as
i know. Model airplane dope works also, but takes a lot more coats than Poly
varnish does and the fumes and the price is not cheap.
If you use Envirotex or other 2 part systems, just gotta follow instructions
to the letter. Mixing seems to be the part most beginners fail at. If it
says dont use below 60 degrees, then i would want to be at least 70 degrees.
you cannot cheat and get away with it. I wind my coils on a lathe with a
special set-up so if i loose a coil, it wouldnt be a great loss, but for
many it has taken hours to get the wire on right, a bum finnish spoils a
lotta good work. cul brian f.
