JoJora If you connect a charged HV capacitor guessing a couple hundred volts, a couple microfarads between G2 and G1 or focus, you will know if tapping the neck results in a momentary short! If the EHT voltage drops, then the electrons will be accelerated less and will move through the deflection field at a lower velocity. It enable to turn on or off the main power. This is called flat-bottom period or pulse interval. The reason is that the drive conditions will now be wrong most likely underdrive and the transistor will overheat from too high conduction losses.
