Standard linear amplifier according to the standard connection conventional circuit configuration, the power of the beam tube tube according to Figure 1-8, the river. The output stage uses power tubes EL34, KT88. KT100 and other radio beam tetrode,
belongs to a class AB push-pull amplifier circuit as early as the gate bias circuit is neither completely fixed bias, is not entirely cathode bias, instead of using semi-fixed bias pressure way. When the output tube using EI.34 as push-pull amplification, each output power up. 40W 2; using KT88 push-pull as you zoom in, each output power up to 60W 2; when using the KT100 as a push-pull amplification, each output power up to 80wX 2.
