1. The 6BG6 is a real possibility.
2. Test the "doorknob" by removing the CRT socket, run the TV for a couple of minutes, shut off and see if it retains a charge at the anode. You should test at the 1B3 bottom since disconnecting the anode will eliminate the capacitor formed by the CRT aquadag coating.
3. Check the resistors under the 1B3 if/when you replace the doorknob. There are usually two. One is a low value (2-5 ohms)filament dropping and the other is a high value (470K-2.2 meg) filter. They don't need to be exact; +/- 20-30% is OK for now.
5. Remove the doorknob and see if you get any more high voltage. If everything else is OK, the TV will work without it. (There may be some other minor symptoms.)
6. Do you have a chassis or model number?
