Sure, Captain, even I missed it the first time! Regards, Nandu.

wavrider's 'armour' is a must if ElectronTubesRule actually follows through with his statement on connecting the capacitors across the AC output of the HV transformer! 73, Nandu.

Using capacitors in series is not about load sharing or getting needed values. It's about not exceeding the voltage rating of each capacitor. Consider a 500VDC power supply requiring a 16μF filter capacitor. Assuming only 32μF 350V capacitors are available, 2 of them in series would give...
