FIELD: radio engineering; electronics.
SUBSTANCE: invention relates to radio engineering, particularly to low-frequency tube amplifiers. Amplifier includes preliminary 1, driver 2 and output 3 cascades, glow circuits 4, anode circuits 5 of preliminary cascade 1 and anode circuits 6 of driver cascade 2, connected to common power supply 7 based on low-power transformer or pulse power supply unit, wherein anode circuits 8 of output cascade 3 are connected through multiplier 9 to supply network 10. Galvanic isolation of output cascade 3 from supply mains 10 at input and output is performed by interstage 11 and output 12 transformers respectively.
EFFECT: improved weight and size characteristics of a tube amplifier with simultaneous improvement of sound quality.
