Hi all,
i got this psu from ebay non working,
i found the volts course pot busted off of the pcb,
its a skytronic 650.682 0-30v 0-10amp,
i think this may be the schematic to it but not sure,
i replaced the pot but it does wierd things,
it goes into cc mode and relays buzz ,
i found one zenner marked bzx550,
it looks like 12v,
it has a vf in one direction of .9v and .8v in the other,
would this cause the issues?,
attatched possible schematic,
would that be the diode marked v12?,
the schematic isnt very clear,TIA
