Hi JZ,
Your fine. The cathode is going to be positive when measuring from the b- rail (- probe on the - rail). Note the ecap there if it was -on the cathode the cap wouldn't like it at all! If you connect the meter - lead to the cathode and the + to the control grid you will see the - bias voltage (the -6 or so).
If you touch the grid pin of the 14B6 the spkr should buzz like mad. If it does I would go on to the alignment. If not you may want to check the spkr, the voice coil maybe rusted to the metal pole inside. This makes cone pretty much frozen in place.
Something that looks that good can't have much wrong!!!!

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.
Circa 1966
Now I think I've got!
