I have a flyback from an SE/30 with exactly such a broken bar. I replaced that flyback from a NOS flyback I purchased way back around 2006. Sadly, nobody makes these anymore, and it's really sad because the flyback is the SINGLE MOST NEEDED COMPONENT of any on the SE and SE/30 Analog boards.
Supposedly, it's structural, not electrical. That bar makes sure the Flyback doesn't vibration itself into oblivion. A broken bar flyback may work fine all the time, may work fine only sometimes, or may never work at all.
Of course, many of us have multiple Analog Boards so we can use it least one as PARTS. So if you were able to swap flybacks, even for a temporary time, in order to test, then such could determine if the flyback alone is the root of your problems to date.
