I found that, while the traces didn't LOOK open, some of them actually were. I found two that were open, so I used jumper wires to bypass those open traces. That fixed the synth.

You can replace the nicad battery with a standard CR2032 Lithium battery with a diode in place so the lithium battery does not receive a charge from the synth charging circuit. The battery would explode without a diode in place.
