Variac

[john]

There's at least one variac that provides isolation (or is it an isolation
transformer
that provides variable voltage?)

Regardless, it's even a Heath, and can be seen (at use on my bench) at

http://www.old-radios.com/radios.html.

There's also a receiver there I'm trying to ID, if you'd care to take a swat!
