LM317T Voltage Regulator with Pass Transistor

www.vintagecollectiblememorabilia.com has acquired a 1920's Master Violet Ray. This medical therapeutic device is also called a Quack Medicine Gadget, for reasons of having special effects but no medical healing powers. Unique and hard to find in working order in this condition; all parts are present and both clear glass tubes are in perfect condition. The main body, massage unit, plugs into a 110 volt 20 amp. outlet, (household plug) and has a voltage regulator knob on the bottom. Adjusting the voltage knob increases or decreases the neon violet ray's intensity. Resembling lightning or sorcerers magic ball, as seen in science fiction movie, this gadget would be a great piece to add to your collection.
