Pulled each tube starting at the left rear (left being opposite the tuner) and worked my way toward the tuner. Of course the last tube tested, (4LJ8) in the tuner had an open filament. Murphy's Law! I searched through the tube inventory and found a good used replacement and popped it in. The tubes lit up and I got a raster. I let it sit for about 30 minutes to stablize and then did a few adjustment and was rewarded with a very nice picture. I dont know why the photo has so much grainyness. Screen looks much better in person.

Bob,
I'm sure you're aware that the early GE Portacolor sets used the same size dot pitch as their large screen color sets. This produced a somewhat grainy picture on the small screen, lacking the sharpness you might expect. I recall buying, from the GE distributor, a GE Portacolor set the first day they went on sale. I noticed right away the lack of some detail in the image.
