Thanks for the tips mike. I just checked the chart, and this tube is the 1st color amp. Actually, I started looking for one this morning. ive got thousands of NOS tubes, not one single 6JG5 though, not even in boxes of loose used tubes. It must have been one of a kind for this chassis. I do have a 6DN3 paired with the 6JH5.
I put the set back together last night to try it out, knowing that the 6JG5 needed replacement. I powered it up, and got about 5 seconds of a raster, but bloomed away and the 68 ohm resistor on the 9-49 module went up in smoke, as did a 2.2k under the chassis from cathode to ground of the 6GH8 oscillator. Didn't pop the breaker in the cathode of the 6LB6 though. I useds a sans-a-fuse in its place just in case it wants to pop, and I don't waist good bel-fuses should a problem arise in troubleshooting. I tested the 6JG5 again, and now its got an H-K short, but I can't see how a short there could fry up those resistors if in fact that was the cause for the failure. I checked lead dress, but I did not disturb anything under the chassis. Tint and color leads are proper too, as I had the tuner out. Nothing shorted out there either. Very interesting problem here.
The troubleshooting will need to wait as I have to buy a tube on ebay and go pick up some resistors.
