A transformer with an open primary winding.
We index mark and carefully remove the old core for re-use in the rewound transformer.
The transformer is carefully unwound to count turns, measure wire size, and determine interleave pattern.
Using the information gathered during the unwinding process, a new coil is wound.
Teflon lead wires are added in the original colors.
The coil is varnished in a polyester resin.
The original core is installed into the new coil. The assembly is then baked in an oven to re-set the wax impregnating the core.
Coil wedges and end bells are reinstalled to finish the transformer..
