I am thinking you might be right about the battery pack being in-house. You would think that at $13000 1990 dollars someone would still have the unit and battery pack lying around somewhere. I can not be the only human on the planet with this player. At least I hope not.

Can you get a schematic for this unit? That might offer a useful clue.

I tried that and they were quite kind but could not provide the answer. I keep looking for someone to be selling one so as to ask what I could do. If anyone sees an add please let me know.
Again thanks to everyone trying to help!

I am just afraid if I do not find the answer a piece of audio history will fall by the wayside, let's not give up.
Thank you everyone!!
