Alos check the output capacitors. A dried up one will
cause all sorts of
problems.
All the capacitors of this power supply were replaced, all semiconductor
tested, various control done ....
but the problem remain the same : the outputs are a few low , sufficent to
trigger under voltage protection.
With under voltage protection disabled, it work without problem with a hard
load.
Now: it's correct to adjust the trimmer R18 to obtain correct outputs ?
I'm not able to understand what i changed in this supply, maybe the sign of
the time :)
Alberto.
