摘要
The primary of a transformer with a high leakage inductance is coupled to an unregulated alternating voltage source. The output voltage from a secondary winding is full wave rectified by diodes and filtered by a capacitor to provide a voltage for the audio circuits. The voltage developed in another secondary winding is full wave rectified and is filtered by a capacitor to provide a voltage for the tube grid circuits. A separate winding is used to provide the EHT supply. The output windings are tightly coupled magnetically and their output voltages are controlled by a saturable reactor connected to the tube grid supply winding. This reactor comprises a winding on a magnetically saturable core and coupled to a resonating capacitor. A permanent magnet polarises the core to stabilise the output voltages against temp. effects.
