[R-390] Question about VARIAC

[rbethman]

Barry,

Connecting the entire set of windings to the input and dialing it down 
the the desired output voltage is "just" what it was built for.

You WON'T go wrong that way.

I've got a MONSTER Superior Variac that will run at LEAST thirty Amps.  
Use it to dial down the line voltage to the BC-610 or the T-213.   I get 
it back down to the "original" 110V that they want.  Its wheel is as big 
as my lawn tractor's!  It is also capable of going 240V hookup, with a 
somewhat reduced current load.
