A couple of years ago, or more, I got an electronic vibrator, ( insert joke of your choice here), from a place in Florida. I think it was called antiqueautoradios.com, or something like that. It worked real good for a while even though there was no hum. One day it melted because I didn't change the capacitors like I was supposed to when I put in the vibrator.
I did remove the old capacitors but didn't replace them, so now I don't remember where they go.
Nice looking radio with a new dial glass sittin on the shelf. Real quiet like.
