Hi, anyone know how to calibrate this power supply? It is out of specs at the higher voltage range. I can't get the information from the seller Kaito (usa). They say they can't get the info from the Chinese factory. I've attached the diagram of the power supply. If someone has a service manual, I would be very glad if I can have a copy. Many thanks for information that can help me to calibrate this unit.
