Sams says that winding is 1.1 ohms, not sure if thats close enough or not, I don't remember if you have the original FBT in there or not.

You may want to do the same resistance test at pins 13-14 on the FBT, if its noticeably lower than the 1.8 you saw at the socket, it may be a sign of a lose solder connection.
At this point it would have done you good to have an oscilloscope, to see if you had the good signal at 300v at pin 6 on the convergence socket.

That would go a long way to sorting this out.
