Schematic needed for SMPS Mean Well PT-45

[RoGeorge]

I have a few Meanwell PT-45B triple output power supplies (mains 90-220V AC to 5/12V 45W DC) left from another project, and I would like to modify them for other projects and other output voltages.  So far I could only find a block diagram and the specs:  https://www.meanwell.com/productPdf.aspx?i=660#1

Can anybody help me with a schematic for this model, please?

No expert on this, but following other threads I think it's been said that
you may adjust SMPSs up to +/-20%. For more than that you may have
to rewind the transformer etc. Some photos may also help.

Found so far a schematic for PT-65.  Components arrangement on the PCB looks identical with PT-45.  I didn't check the parts values yet, but I guess it's the same schematic used for 65W instead of 45:  https://radioskot.ru/forum/3-6666-1
