Since it's an AC/DC set, with a capacitor and high-value resistor from line to chassis, I wanted to make the set a bit more safe. I got some nylon bolts and J-B welded some metal nuts to match over the existing underchassis mounting tabs. The nylon bolt heads are exposed underneath the radio. Found some thick round felt pads at Lowe's and stuck on under the four corners. I installed an .01 mfd cap in the line that goes to the external antenna connection. Finally I made a back for the set from 1/8" masonite: six 1" dia. holes with a holesaw in the drill press, and some saber saw work. Now there is no exposed metal that could go live or give a tingle.
