I have an MTC9000 MZ monitor.  According to the various schematics available:
MZ chassis' flyback PT No is 28021200
BZ chassis' flyback PT No is 28026030
I have a MZ chassis with a blown flyback (has been working for a number of years).  The sticker on it is 28026030 which contradicts all the schematics.  I don't have the history of any previous repairs.  Are these two flyback's interchangeable?  Was this common on the MTC9000s?
Any advice would be appreciated.
