-100V bias for electron tube amplifier

01:17:07

Electron tube amplifiers needs high negative voltage bias to driver and output stages. This bias source can be supplied by rectified filament heater winding of mains transformer.

Во многих схемах ламповых усилителей звука для предвыходных и выходных каскадов требуется источник высокого отрицательного напряжения. Данную схему можно запитать выпрямленным напряжением накальной обмотки силового трансформатора.
