Variac Autotransformer - $75 (Danvers)

. Awesome vintage Variac in good working order Great for vintage amps that were made to run at 115 watts. No need to worry about plugging your gear into an outlet that you might not trust. Avoid power surges that may damage amp components. Running your amp at 105-110 volts allows your amp to break up earlier and adds a natural compression. The Variac has been used by legends such as Ritchie Blackmore, Eddie Van Halen, and Jonny Two Bags just to name a few! General Radio Company Concord, Mass USA An autotransformer is an electrical transformer with only one winding. The "auto" (Greek for "self") prefix refers to the single coil acting alone, not to any kind of automatic mechanism. In an autotransformer, portions of the same winding act as both the primary winding and secondary winding sides of the transformer. In contrast, an ordinary transformer has separate primary and secondary windings which have no metallic conducting path between them.
