Now, if only I could find a tube shield for my 90 Lowboy so I could test it out..
There's lots of way to skin that cat. Soda pop cans with the top cut out and a large hole in the bottom to clear the grid cap, soup can with the top and bottom cut out, or even tin foil is fine. Just two things, ground to the chassis and make sure that there good clearance for the grid cap. If you short the grid cap nothing bad will happen it just kills the signal. I'm pretty sure there are repros made for the 20,70,&90.

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!
