Photographed the current state of the mechanism. It turns, albeit not super easily.
DeShawn found a video of some owner talking about repair and maintenance of these. He emphasizes that poor alignment can cause the hammers to crack the irreplaceable aluminum plate at the bottom. As best I could tell, our plate is intact.
Removed old System 1 power supply board for reconditioning with the capacitors, etc, that came in from DigiKey. We will be following recommendations from here: https://www.pinrepair.com/sys1/
We found one wire to this power supply board had been broken or cut near the Molex connector (see photo).
Right now, it is hard to be certain how to separate the board from its metal backing plate. Olivia and I believe we need to desolder the transistor on the back side of the backing plate.
This power supply board is nonstandard, and has clearly been worked on before.
I tried picking the lock to Hulk’s backbox, but the lock was fairly new and I failed. So, Olivia and I drilled out the old backbox lock. Olivia installed one of our standard locks.
