OK, along with the new year about to unfold, so too is a new part of my audio addiction/sickness.
I'm venturing more heavily into tube gear and am bidding on old crappy tube preamps that I will either blow up or get working, while learning and having fun doing it (I'm having visions of Ben intentionally vaporizing various MW's by applying 220VAC) :D.
I understand the concept of a "Variac", but don't specifically know precisely where to connect it in circuit.
I'm assuming the original transformer leads are disconnected and the Variac leads substituted, then the power very slowly dialed up to whatever the output of the original was if nothing starts popping or smoking ???
I see cheap and expensive Variacs offered here and there. Suggestions?
As always, Thanks In Advance guys.
