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.
