My local scrap dealer has various spools of Litz wire weighing from approx 4-10 lbs. ea. in gauges ranging around 3/30, 5/32, etc. Some of the spools are chiped and some have some dents in the outer layers of wire but all in all it should be useful for winding a secondary to expirement with Litz wire. The asking price is $2 per lb. Email me off list if you are interested.
