[QUOTE="fredeb, post: 765117, member: 13623"] Alright - after wondering endlessly about the various configurations of voltage doublers I've seen on the net and youtube , I decided to just copy the Sansui one , and here are the results : [IMG]http://i258.photobucket.com/albums/hh250/fredeb777/Valve%20Research/Sansui%201000A/IMG_20170313_200037.jpg[/IMG] 1 ohm , 2 watt resistor in series ( to measure current I guess ) . With 2x 220k 2watt resistors as voltage dividers over 2x 330uF 450V caps . Everything seems to be cool and stable . Does everything look right ? Can I add 2x 470nF 630V Poly-something caps over the 2 big caps for extra-added smoothing ? ;D [/QUOTE]
