Excuse me but I'd like to know if I did say something false or stupid in my previous message ? Don't want to sound rude, but if my idea is wrong, my ego can handle it as long as someone corrects me (and write it!) ;) Thanks > > --- In vintagesynthrepair@yahoogroups.com, "cpt.zilog" <cpt.zilog@> wrote: > > > > Hello guys and sorry to jump in like that but I would suggest to change the big caps as a priority and then check the bridge rectifier again for leakage of AC current. > > > > I had a big problem with a D&R console's psu in which the voltage regulators kept on going Kapput. Turned out that the big Electrolytics were bad and that induced a big stress on the rectifier bridge, which in turn had the consequence of not only letting DC pass as expected, but also AC at the same time ! > > > > I did test for AC leakage on the rectifier after the newly installed voltage regulator worked for a couple of seconds before shorting... > > > > After new BIG caps, new bridge rectifier and a 2nd new voltage regulator, everything was sorted. > > > > Good luck ! > > >
