Hi Me ;-),

Look for a "box" or odd shaped molded plastic thing with a thick high
voltage wire stringing up to a tap in the side of the picture tube.  It
will be mounted to the main board with many pins at the bottom.  Probably
wrapped in high voltage warning labels.

They usually have many low voltage windings to run other stuff in the
monitor.  It may be hidden inside the voltage multiplier/rectifier since
they like to combine that stuff into one object these days.  It is probably
a thin plastic box that is back filled with dielectric molding compound.
In the good ol' days it was a fairly open ferrite core with an obviously
waxy high voltage core and a primary with many taps.  The cone thing is the
deflection yoke on the neck of the picture tube.  With so much stuff
combined in and around the basic flyback, stuff gets complex.  Maybe just
get a nice NST...

Of course, if your are looking in flat screen LCD monitors... ;-))

Be very careful of the tube holding a deadly charge despite the fact it
should discharge by itself.  Also, the picture tube could explode with
terrible violence especially from the rear side...  Best to read all them
little labels and take care...  I assume you will not X-ray yourself too
much or eat the lead filled glass :-))

But really, the flyback has too little current output.  Better off with
even a car ignition coil.  I would take the old monitor to the recycler and
start looking for a nice little NST...

Cheers,

	Terry
