Neil asks:
Would a 3 ft long insulated screw driver and ground
wire going to a
cold water pipe qualify (yes that's how we did it at a repair center)?
I hated those loud bangs!
The CRT acts as a big capacitor, and stores a substantial charge. Even
if discharged, it will accumulate a charge over time.
If you just ground the second anode to a cold water pipe, that will not
discharge it, unless the frame of the CRT is also grounded to the pipe.
