Audio - tube amplifier, stereo - or multichannel - amplifier arrangement as well as the method

摘要

Audio - tube amplifier (12) with at least one an intensifier tube (26, 50, 82), whose output is connected to an output transformer (10), which is connected at least one output transformer is primarily - and an output winding (wp, wl), which tube amplifier a compensation control (20, 22, 28, 30, 32) with a direct current source (20), which has, with a compensating-field winding (wk) of the output is connected via this support, in order to produce a compensating magnetic field, the the by the dc current component in the output signal of the magnetic field produced an intensifier tube is in the opposite direction, wherein the direct current source at least one clock-controlled electronic switching element (t1) contains.
