Neat solution Kai you could also use four separate transformers to charge the capacitors and paralel the primaries use a common metal mounting plate to to keep the cores connected. only problem I see is any leakage through the rest of the circuit will cause the voltage on the lowest leakage cap to rise. so for safety a set of bleeder resistors is still needed but now the must only compensate for external leakage. I would still test it remotely as loud bangs hurts your ears. Still a most effective solution Terry
