Hi all, I have just brought this psu,
its o-30v 0-1a,its made of discrete components with no ic's, its transfo has a center tap then +50v,+40v/-50v+-40v taps with a seperate 6.3v winding , the main voltage pot is a 1k with just the center and one outer leg used,its 1k at max volts,would it be possible to mod this for say 2amps and 70 ish volts output? would anyone have any ideas ie schematics etc,or an explanation of its circcuit topolagy,it has a wirewound resistor of 1 ohm,i assume that is a current sense resistor,i have uploaded some pics of it in the photos section called my psu,cheers in advance 73 Paul de m3vuv.
