    I'm trying to identify the type of flyback transformer in a Mac Classic unit to see if it can be used for Tesla coil type projects. I read this guide: http://boginjr.com/electronics/hv/flybacks-guide/, thinking it matched #3, but the guide states that those types were discontinued in ~1978. Of course, the Mac Classic was manufactured in the early 1990's, so I ruled #3 out...

    Can anyone identify this type of transformer?

    Well it appears to be a typical Flyback TXFMR C.W. rectifier in series with the CRT anode lead.
    There is one principle winding that it is driven from, the rest are usually secondary supplies or output to the Horiz. scan coils

    So due to the rectifier I assume this outputs DC which is not suitable for Tesla coils? Could the rectifier be removed somehow?

    Can't quite see how it is connected to the secondary, if you can locate the connection, just remove it.
    You will need to make sure any connection is very smooth, clean and covered with heat-shrink etc, so you don't produce Corona, (that's not the beer BTW!).
