[QUOTE="Byrd2, post: 68386, member: 384"] Secondary 2 looks like it is now going to be producing 38Volts DC (instead of 28Volts) if the measurement you have taken is correct 55 / 2 * 1.414 = 38.885 You should have read closer to 40 Volts on that secondary. What are your DC voltages. Either side of C901 & C902, Either side of C905 and C806. At least I think it is C806 as I can't read that schematic properly - either way it is the matching 470uF 35V capacitor for C905 where 1 leg of each capacitor meets on the ground rail. Could well be the bridge that has gone. [/QUOTE]
