Hey folks!
I've got a dead Whatsminer PSU on my hands, specifically the P21D model.
Just curious if anyone has found a circuit diagram or schematic for Whatsminer PSUs and would be cool enough to share it.

There is a service manual in coursehero but they are selling it but I tried to search a bit and found a p21/series PSU service manual that includes a maintenance guide and schematic diagram.
Not the exact PSU model number but I guess all of them are the same P21D, P21C, and P21E.
