ABSTRACT:
A transformer-coupled amplifier includes a driver transformer in which a primary winding, a secondary winding, and a tertiary winding are wound on a core of a magnetic circuit, a drive signal source for supplying an AC drive signal superposed with a drive-stage DC current to the primary winding of the driver transformer, a power tube for extracting, from the secondary winding of the driver transformer, an AC signal corresponding to the AC drive signal supplied to the primary winding of the driver transformer, and for amplifying the AC signal from the secondary winding, and a DC magnetization control power source for supplying a predetermined magnetization control current to the tertiary winding of the driver transformer so as to change a degree of DC magnetization of the core of the magnetic circuit of the driver transformer. The DC magnetized state of the core of the transformer magnetized by the DC current is appropriately changed by the magnetization control current.
