Are you sure that diagram is correct because you seem to have a coil between the positive and negative of the bridge rectifier via the connection where it says .14
That can not be correct as this would produce a DC short or near as damn it.

Thanks Rich, I totally screwed up.
Fixed and updated the first post (also below).
Squiggly line is the inductor coil.
Yellow wire is a sensor wire that solders to the copper on the protective tape around the inductor coil. Unwrapped and verified this is not the short, BUT resistance is .22 across Q2's D and S.
2 green dots are on a very small transformer. Resistance is .36 across these two dots which seems expected when the wire is simply wound around a magnet. However, From either green dot to the two question marks on the same small transformer I have .5~.8ohms.
Pulled Q3 and Q4 and they both bench tested fine with 12v. Used a small .2 amp fan.
Variable power supply in 12v, 5v and 3.3v
Considering a cheap chinese one that you unplug when you leave the room.
When I plug PS into my 100w light bulb safety device the bulb glows like I have stuck a nail across the outlet terminals.
