Lab Bench Power Supply – Repair / Schematics – Generic or UG-6010DC or Axiomet AX-3003L

Dear all,
I am in process of repairing a bench dual power supply of the type UG-6010DC or AX-3003L-3. (Link : https://grobotronics.com/power-supply-laboratory-3-channels-0-30v-0-3a-axiomet.html ). These are standard bench models found in labs, 2 variable output supplies (variable current and voltage) with Master/Slave control and a 3rd 5V fixed output. These models are 30V, 5A per channel and 5C,3A. (Image attached).
I would appreciate if anyone has the schematic of such model or a similar model to help me in its repair, I believe that there is a standard schematic around with different variations,

Thanks beforehand,

I did a quick Google search for "lab bench power supply schematic" and there were several pictures and other information that came up. I'm not sure if  the model you are looking for is among them.This looks like a commercially made lab supply so the schematic may be available from the manufacturer.  If not, we've got a few experts on here who can help in troubleshooting.
