I've never saw a list of types with data or compativility list for FBTs.
The best your proably can do is looking for another CRT Monitor with an
similar Voltage (28V) as the power for the horizontal output stage and
look at the schematics of that monitor how the FBT is to be wired to the
CRT and the deflections coils. ..then try to get such an transformer
from somewhere...
