I've worked on TVs and radios for years just by identifying what prong is connected to the chassis, plugging it into the neutral side of the receptacle, and then lifting the ground on my test quipment to break the ground loop. Never once shocked myself, but I always checked voltage to ground before touching anything. There's no way I'm the only one to do it this way, it is obvious and easy, but only one mistake away from a shock. It's nice to get rid of all that nonsense.
