Guys, I had the low voltage power go bad on a LPS I am repairing so I took a shot at verifying the 24/12/5V power on our schematic.
Notes:
The LV transformer is electrically correct but not sure about its physical /magnetic configuration :(.
I was driven insane until I figured out that the 7812 and TL431 parts are SOT-89 whose pin-outs are literally backward from standard parts.
…
The new section + some updates are on the shared schematic.
