Re: [TCML] ANother tube coil question

Hi David,

I don't know what it costs.  I think some folks use
thinner litz wires, and simply parallel a great number
of them to create a thick enough wire.  They
create a sort of bundle that way.  I'm not sure
if Ed made his that way.  Theoretically litz wire
could be home-made by paralleling many thin insulated
regular enameled wires.  If the wire is the Soldeze
type then enough heat would remove the insulation
at the ends so they can be all soldered together at
the ends.  I think some folks dip the ends into a pot
of molten solder to solder the ends.  Seems like a big
job though.  I think they use something like 36 or 38
awg wire for the individual insulated strands for
standard litz wire.

Hi John,

Thanks for your response. We both saw Ed Wingate's
big tube coil just a few weeks ago ;^) I do recall him
mentioning the Litz wire primary, now that you mention
it. Isn't Litz wire very expen$ive, though? It doesn't seem
to show up that often on eBay. I can only imagine how
much 50 ft. of #8 Litz wire would set my wallet back!
