41-608 no radio stations
#24

Let's start here  http://jollinger.com/radio/tubes/tube_basing.html
Study the octal/loctal base note the pin location vs the key. This is how you count the pins on these tubes. What we are looking for is voltage on pin 3 of the XXL. Should see some hv there. On the 7B5 we are looking for hv on pins 2 and 3. Pin 6 we should see some - voltage, a few volts.

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!
