hi everyone,
from this morning my bench power supply (ps 305 d) it does not work correctly.
the output voltage is without regulation and it is to maxim (32 volts).
on web i found a diagram similar but my power supply have some different.
the diagram have an lm324 (u104) and another ic (u105) that i don't know (think another op-amp)
while on my board there are four ic.
two of these are lm 301 an , but other two i can not see the label.
i attach the schematic that i found and the images of my power supply.
thank you so much for any suggestions
