I removed the HV cage and disconnected the 4 wires going to the flyback.
After removing the 1B3GT plate wire along with the 6BQ6GT plate wires and the door knob cap and 1B3GT socket I ohmed out the coils. They checked good. I then cleaned up the coils by removing the melted covering by chipping it off and using heat to melt it some. I used a lot of Q-Tips and acetone. I then cleaned off the yellowed cad plating and cleaned up the rest of the assembly.
After cleaning I then baked the assembly at 225 degrees F for several hours. I then used my MG chemical Super Corona Dope and brushed on 4 coats. 1 coat on one side then bake for an hour, the do the other side and bake it again for an hour. This was repeated for 4 coats. The coils are just about filled and 2 or 3 more coats I'll be done. Stay tuned for the results.
