Man that sounds scary....wonder when they finally started polarizing?
My dad has his dad's old Zenith stereo from about 1960....tube type, record player and all....looks like a piece of antique furniture....reached down inside one day to turn up the volume and got zapped when my hand brushed up against the metal face.
In the owners manual it says if you hear a humming instead of music to reverse the polarity of the plug....
