This device is especially suitable for applications in audio·amplifier circuits, in which it may be used as either driver or output unit. The 200·watt amplifier shown in Figs. 1 and 5 uses eight RCA 1B05 transistors, two as drivers and six as paraliel units in the amplifier output stages. These devices are employed in conjunction with eleven other discrete transistors, twelve diodes, and a 160·volt split power supply. The amplifier output is directly coupled to an B·ohm speaker. This 200·watt audio amplifier is especially designed to feature ruggedness in combination with high power output and excellent high·fidelity performance. I CLASS A ...
