Hey, I've got good news! (its not geico)
I just replaced C1507 22/50V cap.
Guess what?
Seems to be working now , at least with my dummy load I can bring the
voltages back to normal.
It's late so I wont be hooking it up to the scope today, but I think I've
got it.
I'll report tommorow night.
Thanks guys!!



I hate to say " told you so ", but when you first posted on this back on the
18th, I said to run an ESR meter over ALL of the electrolytic caps in there.
I probably didn't make it clear enough that I was referring to the little
fellas on the hot side as well as those smoothing the rails themselves,
although I did say suspect any that are near anything hot - and I bet your
culprit is. I work on switch mode power supplies of all flavours all the
time, and in at least 80% of cases of faults that are not obvious blow ups
or diode failures, the cause is an ( often primary side ) electrolytic. My
first check for a dead power supply where the fuse and startup R are ok, or
one that's doing anything odd, is to run the ESR meter over every damned
electrolytic in there. That one little test instrument has saved me so much
time and money over the years. And don't worry, that hair that you tolds us
that you tore out - it'll grow back !!

Seriously though, glad you've got it going.
