Absolutely awesome, takes me back to when I was building radio equipment from ex war department sales. Getting a variac like that would be very difficult right now.
Last time I used one it was controlling a pair of Imac 3-500's vacuum tubes.
How do you find time for all that stuff when you have sheep and wolves ?
