Success! I did the resistance checks per the chart in Sams and found V5 pins 5 and 6 showed open when they should have had 2.6K to pin 8 of the LV rectifier tube (120V). I checked the schematic and R29, a 1K resistor, was between the tube pins and 120V bus. I then did a visual on the resistor and it looked good. I then bumped it with my finger and a lead pulled out of the resistor! I replaced the resistor and now I have very good audio and video through the antenna terminals.
I have to finish replacing the rest of the resistors and a few micas yet. But getting a good picture and sound is very encouraging.
BTW, the CRT, a 14CP4 tested very low on my BK 467 but played in my AMC TV came up real good with a very good life test when I gave it to my friend who has a Beltron. He rejuvenated the CRT for me.
