While repairing power supplies, I made pictures of the boards and labeled the aluminum electrolytic capacitors with Value, Voltage and Designator. I also labeled some other devices and added some notes on a few.
These are for WMS, IGT mostly. I hope to add more as I repair other supplies.
I hope these are helpful. The schematics and manuals are located in the NLG File System - Download section.
Email or PM if you find errors or have questions.

Funny how they print different caps onto the boards.....same boards, different caps for different voltage PS units.

Yes, one board, many styles, just add components for what you want.
Of course, I needed a lower and had an upper that gave me problems. Was going to convert it - too many differences. Gave up after looking at the other components. Could be done I'm sure.

For those of you interested - you can replace the original PS with an inexpensive 12V 2.1A PS from Mean Well. PN = RS-25-12
XP Power LCS35US12 would fit with modification to allow power cable to seat in slot correct - 12V 3A

Tony,
STILL one of the best posts on NLG on these power supplies. I find myself coming back to this often...I should bookmark it! haha

This is GREAT! what an excellent idea that will be helpful for many.
I believe that this is what is wrong with my Game King. I am going to pull the PS and replace. I will post pictures if it is not one listed above.
Thanks again Tony!
