I have wound up perhaps 30 transformers on the BN202-73 cores over the last
three years for myself and friends and have had no problems with shorted
turns. I have used #26 enamel for the 5-turn windings and whatever small
insulated wire I have on hand for the 2-turn winding.
I have not found one core with a rough edge (all my cores came from Amidon),
but to be sure I do not pull the wire tight to the core. I check each
transformer after winding and "Goop" the leads to relieve stress.
Are we making a mountain out of a mole hill here?
Bill, VE3CSK
