I tried hooking AC directly to a de-vibratored 50-51 Ford car radio once. I got a very loud SPLACK
as the copper "spark-plate" capacitor promptly did its job, routing the offending AC to ground!
BTW, most vibrators run at 110 Hz, IIRC. Pull the Sams' for that set and find the power xfr ratings, then go buy the closest one you can find. And watch out for the 1-1/2" square copper spark-plare, if used!
