Hi Rich,

Yeah, read the specs after I posted. Does it come in that can or did you package it. If the latter, Great Job!!!

Are there fingers that grab the can?

One thing to try is to measure the freq of the mechanical vibrator. Seems from the notes form PeKo that the vast majority of commercial vibrators are 115hz. if the mechanical vibrator is vastly different, then the buffer cap may have to be replaced with one of higher capacitance. Square wave notwithstanding, this should be a rather low frequency hum, similar hum to that of a radio with a full wave rectifier with bad filter caps. If much higher pitch, I am scratching my head.
