Gents
I may be stabbing in the dark but i have a theory to share with you all
with my experience with high frequency power supplies and with skin
effect prevalent would it feasible to use multi-filar enamel wire for
the primary
that being said would it not be wise to use lets say around 10 - 12
strands of 0.8mm dia or whatever is needed to get same approximate
copper cross section required therefore the skin effect is reduced to
a percentage or each strand rather than a percentage of a single
copper mass
not sure if i explained it clearly but my 2c worth anyway
