The TV that use a metal CRT have capacitors as part of the HV circuit, those store a charge that you should discharge to ground, by connecting the bell to ground. So if you use the 10BP4 make sure both the anode button and the ceramic HV caps are discharged.
Are you talking about the doorknob 500pF cap that the 1b3 inside the HV cage sits on? I didn't know that could store a charge being such low capacitance.

What would be the best way to make an adapter for the anode lead? I have a spare anode lead with suction cup. What would be the safest way to couple that with the existing single prong anode lead for connection to the 10BP4?
