Thanks Folks,
Reese posted the link to the schematic for this radio in one of his posting (above) and it's real accurate!
After I got some of the Dust balls out I noticed a little funny looking round deal-e-O!.. It's a durn battery!.. Use for biasing the First Audio/Detector Tube (75).. and hooked to the variable arm of the Volume control pot... That's neat!
What should I use to replace this little single cell battery with? It's 1.5 volts and has a part number of 1928..?.. No, I didn't measure this one yet.. I bet it's dead as a door Nail! Nice little holder too.
It's a little hard to see in my picture. It's just South of the Diagonally mounted Blue Ecap and it's on the terminal strip. The holding clip is to the left of the actual round battery.
