I mounted the Frankenstein's Monster of a CRT into the cabinet. I managed to repair a K7000 and replaced the tube with an Orion. I am planning on keeping the original Williams transformer/power wiring assembly that I found in the machine (which is from a Motorace USA) and removing the Williams power supply board, which I am replacing with a Peter Chou SMPS that was also in the cabinet. If I'm reading the schematic correctly this transformer already has an isolation winding in it and I won't need a second independent isolation transformer.
I'm pretty sure I am reading it right, but I am going to ask to be sure because high voltage AC scares the poop out of me.
I'm also going to remove the connections from the transformer that were used to power the Power Supply Board as it is no longer needed, just to keep this neat.
