[ODPILOT]

Just gone done restoring my B1750 radio (1954).  I noticed that when it is plugged in , I can feel a current running through the chassis and the metal potentiometer rods used to adjust the volume and the radio stations.   When I unplug the radio from the wall and turn the plug around the other way, the current is no longer apparent (radio works fine either way).     Obviously, the plug from the radio is non polarized while all the house sockets are polarized - as I'm sure they are with your houses as well.  I noticed the same kind of thing happens with a 1960's drink mixer that I've had since I was a kid (it's called a Vornado Drink Mixer). I   Can feel a current running through it, but when I reverse the plug in the wall socket it goes away.   I guess I should figure out which way prevents the problem and then cut off the old plug and replace with a polarized plug - but what's  up with that??  Thanks
