    As a tester, capacity droppers are wonderful!
    Built a few my self. (I upped the bleeder resistors a little though .)

      yes, i could have gone higher as well.......the capacitor would have charged much higher than 230 though......I thought that was high enough...

      lol...yes i get it and i sympathize....I've had my share of 120 as well....not nice...so in that case i completely agree with you so at 220 RMS , the peak would be 311 volts which means that with a full wave bridge the capacitor will charge way over 450v.......what are the standard values for caps in europe anyways......is it 600 volts minimum????

      @@silectronics I go 600v yeah. Always done. But 450v will do. Might smell a bit bad after a while though =P
      And, the higher values on the resistors, is because I want most of the pixies to go through the cap, and not squeeze through the resistor.
      Little bit slower discharge, but not really noticeable.

      right....ok?....i understand.......well, no matter what country or power levels , a circuit like this one is dangerous and needs to be respected........a rule of thumb for bleeder resistors is usually 10 % of total current......If that helps you to calculate its value, and 90% would be left for circuit operations........those caps sure do smell bad when they go....so using 600 volt types in your country is a much better idea.
