Here's a picture of my build.
After I read your comment, I noticed that the 270 Ohm 5W resistor wasn't soldered in with the rest so I just resoldered terminal 13U with the resistor end connected. I will redo my resistance and voltage readings right now and give you the numbers again.
Also just to clarify, when we do the checks, "the ground buss at terminal 12U means I clip the black lead then clip the red lead to the other terminals for checking right? Sorry this is my first time building anything related to electronics haha
