Philco 70 and similar ground leakage
#13

No because no matter which way the plug is inserted you've got the hot side of the line connected to the chassis thru one of the  two caps. If you connect the chassis to earth ground that will remove the tingle.
The cap that is going from the neutral side to the chassis provides the rf ground for the rf circuits in the set if you don't have it tied to an earth ground. The hot side cap provides the rf filtering to help clean up rf noise on the line.
As for the power transformer acting as filter inductor at rf not so much. There is this thing called distributive capacitance where the windings from pri to sec couple the remaining noise like a cap would. RF noise is insidious!!

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
