Good idea, I normally disconnect the power supply a use insulated pliers to short a capacitor bank with a wire, then tie it together while I work on the circuit.
Microwave oven capacitor have a internal 10Mohm bleeder resistor, it saved me have a voltage balancer network.
I,ve had some more capacity to the bank, I get about 4 a week. I've add a top and bottom magnetic, now the pellet notice ly moves but still not far.
After I get half the secondly layer brought I will work on a test to use potassium carbonate when heated to 800-900C breaks down into CO2,K+,KO, hopeful the ion will breakdown the spark gap.
