Does the det tube look like it's lighting up as bright as the other 24A's? You may try checking the voltage at the tube's pins while the set is operating. 2 1/2 volt tubes pull a little better than twice as much as 6v tubes. Any sort of oxidation or poor contact can diminish the heather voltage and the efficiency of the tube. Right now your 24A isn't hauling down enough plate current to drop the voltage across the plate resistors.

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.
