Putting the battery proved a bit of a problem.

The Stromberg Carlson AWP-8 uses the same battery as any tube Zenith TO.
But somehow when the battery is fully in, the plug is sticking out about 1/4" from it and the back when closed presses at it squishing wires that come out of the plug flat against it. It is right where the manual bag is attached, and the only way the back closes (squishing the wires, and barely holding at the pins) is when the manual is out. With the manual in it just won't close.
It's possible the AWP-8 plug is a bit longer. I don't have any way of knowing if it is the original plug.

I posted a question on ARF plus wrote to Ed Morris.

PS. Yes the plug is about twice as long as the Zenith TO one.
PPS. I could not pkug the AC plug into the slots to enable the battery, as the plug is likely not original and is polarized. So I broke out my dremel and ground the wide prong; now it's ok.
