Grounding the chassis will eliminate this voltage.
3 prong plug in is the solution then i guess, i have 35ohms on my utility ground... so my N leg is fine. My 2011 notes on my panel board say i had no neutral current with my amp clamp either. the garage where i am working doesnt have any motor loads on right now. I'll have to redo my power chord and see if that that helps any.
either way when on short wave i still hear a tiny bit of humm,, it reduces in audibility when a chassis gnd is added.
I was actually thinking the band seletor section is rubber isolated somewhat and thought the error was there. THen i looked again and see Philco has a jumper wire from the chassis of the main section to the chasssis of the tuner section so...... i was wrong there.
on my hallicrafers the rubber isolators keep the exterior completly isolated from the radio.
