Re: Aluminium Magnet Wire for Secondary

Original poster: "Malcolm Watts" <m.j.watts@xxxxxxxxxxxx>

Hi Terry,
          I wound a secondary with Al wire a few years ago to
demonstrate to someone that TCs couldn't be made to go "critical"
with that material. I wound the coil on a lathe and tensile strength
didn't seem to be an issue. The biggest drawback was not being able
to solder the ends easily.
