[QUOTE="fredeb, post: 763290, member: 13623"] Voltage tripler : [IMG]http://i258.photobucket.com/albums/hh250/fredeb777/Valve%20Research/Sansui%201000A/IMG_20170305_191558.jpg[/IMG] Diodes are UF5408 , Caps are Rubycon 10uF 450V 105?C . It looks as I may need voltage dividing resistors across the lower 2 caps as DC is potentially 525V . Would 2x 220K 1 watt resistors suffice ? I'm also wondering whether another diode between 0 and the bottom cap is perhaps a good idea ? Just to be sure that ground is ground . The tripler will be connected to 2x 220uF 450V caps in series , with voltage dividing resistors across them . [/QUOTE]
