    Description

    Vintage Staco Adjust-a-Volt transformer.  120V input, 0-135V output, 7.5A.  Model 500BU-3.
    This one will need some work - the selector ring is loose from the nylon center shaft.  It either needs a clip installed or a new bushing.
    This is a larger unit, shipping weight 9lbs.
    Please see photos for more details.
