Singer HE-2200 Kids Record Player

Would not want you all to get bored troubleshooting quality gear, so here is some low end for you.

I was just gifted a non functional Singer HE-2200 record player from the 60's.  (Phonograph sounds too snooty for this children's player.)  I had one when I was a kid.

It wasn't doing anything except producing sound akin to white noise when I got it.  I was able to free up the seized motor.  Jury is out on the rubber roller for the rim drive but it might be actually be okay, much to my surprise.

But no audio except the white noise.  This thing has a ceramic (mono) cartridge.  I have tried connecting the cartridge to a variety of mic inputs and I get nothing at all from touching the stylus.  To prove the test concept I have taken a piezo crystal headphone and connected to these various amps and I get loud audio including feedback.  Most recent test was going into the solar cell input of a film projector and nada.  I also hooked it to a scope.  So the cartridge must be bad.

But I also get nothing from taking that same crystal headphone and connecting it to the record player's amp.  So apparently the amp is bad too.

There is a remote chance that someone here is familiar with these and may know the common failure point in the tiny three (germanium) transistor amp.

But barring that bit of good luck I'm hoping someone can suggest a very simple (and cheap!) amp module that I can put in.  It would need to work with a ceramic cartridge.  I realize I can replace the cartridge and output to external gear but I'd rather recreate the original self-contained functionality.
