Jeff,
The owner's ideal plan would be to use the set to watch B&W films on a few times a month. The flat panel would be the "daily driver" for all of his other programming.
They would be hooked up separately, sharing a cable box (a/v outputs going to the flat panel, coax out going to an rf modulator for the GE). If I did have to add a/v inputs, you can be sure that even though the coupling caps are all replaced, I would still add a cap to the inputs, to further isolate any solid state gear that could be feeding it.
A few neat items on circuit design in this set:
I found the plate voltages to be 50v too high on all of the video IFs. It turns out that the contrast control is actually a gain control. As you adjust the contrast, you can alter the plate voltage of all IF sections by about 60v or so.
The vertical and horizontal hold controls are in the rear of the set. The literature I have been reading on this set describes these controls as something that only need be set up once, and then left alone. We'll see how much that is true once the set it running. I will say that the vertical height, hold, and linearity interact with each other a good deal. If that vertical hold control was on the front of the set, in the hands of the average Joe, you could probably really mess up the picture.
