Finally getting back to this project.
Having an identical, all original parts chassis makes it much easier to work on.
Especially since Sams only published a schematic for it.
There are two 4-section twist locs buried in the center of the chassis under the yoke support.
Really no room for adding terminal strips or cutting them open in place.
So, I took the time to disconnect and unmount them, cut them open and restuff.
I hope to power it up this weekend and see if that recoated flyback works.
