I can't think of anything that would cause the modulating frequency to shift to double it's original.
A fault in the modulator or some sort of odd mixing of the mains frequency and the modulator. Have
you tried the adjust the IF transformers? Perhaps the IF stage is oscillating.
I would ignore it for now and see if aligning the IF makes it go away. Or maybe it's trousers are just
toooooo tight.[Image: https://philcoradio.com/phorum/images/sm...on_lol.gif]

When my pals were reading comic books
I was down in the basement in my dad's

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
