G07 Vertical Collapse - Chassis is rebuilt and works fine on other tube
So I'm restoring an Astro Blaster which had significant rust/corrosion in the game boards. It has a G07 CBO monitor with no burn. When I picked it up, the monitor was dead. Fast forward a few weeks. I have rebuilt the chassis with new caps, new flyback, new HOT, reflowed connectors and anything that looked sketchy. Add done and the monitor is is vertical collapse. I pull the chassis and test it in another G07 I have and all works as expected. I then pull the working chassis and test it in the Astro Blaster... vertical collapse.
I guess my question is this. Aside from what's on the chassis and neckboard, what else could be causing the vertical collapse? Could this be an issue with the tube itself? Perhaps one of the connections on the yoke is bad? Am I missing something else?
Any input is appreciated.
