GW Instek (or HopeSun clone) GPC 3030

I've been looking for ~ a year, for a schematic covering this very common "triple output" Lab Power Supply.
Anybody know anything about where I might find one?
Thanks for reading.

Welcome to ETO, Hectorpascal!

Subject pops up every so often.

Little more than the block diagram (with some limited component ID and usage):

basically, the unit's User Manual.

Schematic does not seem to exist on the web. Yet, anyway...

Thanks Cowboybob.
I think I have already collected virtually everything available on the web about these supplies!
But I'm still hoping that something useful will surface eventually.
My hope is that it's simply a matter of advertising widely enough that people are still interested in the information.
