Re: Amplifone HV Trans question...

DUNNO, not familiar with the circuit. The point I was trying to make is a "flyback" circuit
depends on the collapse of the magnetic field in an inductor or transformer to provide the
desired output power. If the circuit is arranged like that (like the horizontal output on a
raster monitor, for example) the transformer is being used in the flyback mode.
