John, you are a genius! All is well! I’m going to change the wiring I’my homemade connector and mark the ph180 as parity reversed! THANK YOU!
FWIW, I had one of those bricks with the reversed polarity, I just took it apart and swapped the power plug leads. While I was in there, I replaced the troublesome fuse with an appropriately rated PTC. Serves the same purpose, but when you remove power for a minute, it's as good as new with no screwdrivers or fuse replacements.
