RCA 1-TP-2E is silent!

[Jonathan]

I purchased an RCA 1-TP-2E from ebay a while ago. I purchased it because I ourchased an RCA ad that featured this radio. It is one of those radios that uses RCA's VS149 4V battery. I get a quiet pop out of the speaker when I turn it on, but that is it. The speaker has a center tap, believe it or not, and it's connected to ground. I ordered the Sams and have the djvu schematic from techpreservation.net (I think that's the site). I'm not sure where to start. Possibly someone could have popped in a 22.5V battery and fried some things? I'm powering the radio with 4V from a bench supply. Anyone have any suggestions?

Thanks.
