The vc doesn't do anything but vary the amount of signal from the ant to the primary of the ant coil. On some sets the vc is connected to the ant and cathode circuit which vary the cathode voltage this in turn effects the grid bias.

The short answer is yes you can and you don't need a resistor just a shorter ant or less signal from the sg when making adjustments. It's the same as using the set w/ the vc all the way up.

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!
