hello all, I have gone the distance with this power supply, with no positive results! So far I've changed the strs6301, caps in the soft start cicuit, check the diodes and transistors, but the damn thing just won't start! Oh, and the 270k kick bias resitor is good too!. Also checked for for secondary shorts, but there were none. Anyone got another idea on this? Jim McVey McVey Alltronix 327 Broadway Newburgh N.Y. 12550 "If it doesn't play... CALL MCVEY !!!!!!"
