I thought the output coil voltage would be pretty low, like 5 volts or so.
The coil resistance has to be pretty low.

Yes -- but the coil inductance could raise its impedance
significantly, allowign higher voltages.

However -- with 5 turns and only 100 KHz, probably not that
significant. Of course the inductance is also a function of size (turns
diameter) as well as the number of turns.

The guys from Ameritherm did handhold the samples that they heated. That
was part of the demo; to show how the machine heated the end in the coil so
fast that the handheld end didn't get very hot.

Probably pretty low voltage, then.

Might still want to be careful around something so old. Who know's what
voltages are leaking out of that thing.
