Coil forms ready for new wire

These are Accutron 214 coil forms, stripped of their open coils.

They are the later two wire type, both circuit and cell sides, containing the later NPN transistors. They were all rejects, with open coils. They await a trip through the winding machine.

I rewind with more turns of wire than they originally had, to make them perform correctly with new silver oxide cells, which have a slightly higher voltage than the original mercury cells.
