I have been reading with interest about the filament chokes for 3-500Z,
etc. In the photos I've seen of projects the filament choke appears

Jason --- The Cu wire is insulated with a plastic coating. Modern
electric-motor and transformer wire is insulated with silicone varnish.
This insulation is so tough that is is usually burned off with a
propane torch and the ash thereof is removed with steel-wool.
