I'm gonna' have to strongly disagree with your friend on the point above! Connecting two CW-80's in that manner, or any electronically controlled voltage transformer, is a very bad idea! You would probably get away with it with old PW transformers, though you'd doubtless have to replace rollers more often. Many of the electronic transformers would shutdown (or worse) doing that.
