More of an FYI

Was reading this http://forums.arcade-museum.com/showthread.php?t=202035 and saw
big resistor hanging off the side is crucial. FWIW, I had a chassis I completely rebuilt and neglected to check that, and installed it and it made this horrible electronic burning smell and did nothing. upon pulling it out, the fuse was blown.

after fucking with it for a long time I realized the hanging resistor was CRACKED IN HALF. you measure B+ there if I recall, so it's a monumentally crucial component to the whole chassis lol.

Looks great and tests within tolerance (217Ohms) but had 160V on one side and 1V on the other with power applied. A quick tough wiggle and I knew I had found an issue. Before and after pics.
