Okay, here's what I got. The FBT (T207) is fed via wires from the bottom. From there the wires coming out of it are bare. They connect to points on a white board I'm assuming to be the "terminal" board. I am attaching pics of the board, the terminal guide and the layout of the FB from the SM. I'm hoping from this we can identify exactly which wires need to have the bulb between them. I can see that the focus lead is tied to point 11 of the guide. And it looks like 9 goes back and feeds the collector of the HOT.
