Catastrophic failure mode possible on different hardware

[ctech4285]

Force 1 second delay when power stage misfires. Misfire = main capacitor is not discharged after firing

It is possible on different hardware that the holding current is reached. Via the cathode pull down resistor on the power stage
It cause the Thyristor to stay on for up to 1 second. Subsequently firing its lower pair will cause the two thyristors to eat to much power and fail as short.

I'll take care of it before we change out the thyristors for the next rev
