Thank you good sir. I'm trying my best to learn about all this. When you mention the rectifier bridge, what are you referring to? Does this supposed design fault apply to the 15v rail on all plugs? Presuming that I can test said plugs while the monitor is off, I will grab a MM and check. The ouput voltages are all coming from the top mounted plugs on the G board so testing all the pins should suffice, I believe.
