Hi Rob,
Usually it's a problem w/ the heater string or excessive hv current that will pop the bulb. It has all 150ma heater tubes in it right? If so I'd check around the output tube to see if the plate, grids, and cathode voltage are ok. Then I'd swap the 35Z5. I've got a green one. It's fun to play w/ a pringle tube near the loop when you get it all together.

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!
