PSU wiring help needed

[Boyan Silyavski]

Do you have any wiring diagrams for the regulator board and the transformer? Personally, I'm not too happy about wiring the output of two supplies in parallel, but without knowing what we're looking at, it's a bit difficult to diagnose. I can't quite work out why you are seeing 140V at the output, but a bit more information would help.

Here is a very similar board, seems from the same manufacturer, that has schematics, seems the same with 2 capacitors more, though not 100% sure
