Sounds to me like you either have some strong electrical interference from lights or modern devices. Or a open grid circuit that is causing modulation of the signal. Would try an earth ground connection to the chassis to see if that improves things. Another thing to try is measure the resistance from the tuning cap's stators to the chassis. Should see a low resistance like 20-50 ohms. If much more than that you may have an open secondary on your rf coil (s).
As for the cone typically what a rubbing cone will do is give distortion @ low volume levels and if rubs badly it will give you distortion @ all volume levels.
If your coming up the Ktown stop in a say howdy!

When my pals were reading comic books
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!
