[NJARC] Cleaning metal fragments out of a radio tuner

[Robert Bennett]

 Well……

                Two things - One- I just never saw anything like this. I paused the video when the camera glanced over to the power supply. I figured that if that power supply is not overload protected, this guy would hurt himself! Second - I actually know this guy. I met him a few years ago. I’ll explain the details at the meeting tonight.

Bob

P.S. Maybe someone could show this on a projector screen tonight just for grins….

Like Victor said, it's not defined how its' hooked up (but I'm assuming one side is hooked up to the plates that move and the other to the stationary plates).  I assume this would only be a good idea on "hollow state" stuff...
