Just to clear something.
What Scott is asking is which wires coming off of each electrode go to which pin at the base of the tube. He sees two metal tabs near the evacuation point in the glass that he thinks should have some sort of connection.
I told him that the tube has 5 elements and 6 wires leaving two of the pins blank.
We talked on the phone and some previous repair a 400mfd cap was installed as the input cap in the power supply. We checked out the ac side thing and it's good but on the dc side no dc cathode volt at the rectifier. Methinks the 400mfd cap took out the 25Z6. He has one on order and some caps. The heater string is ok so far.

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!
