This circuit has more historical value than practical, unless the reader find all the components in the output stage of an old cassette recorder 70 or a radio at the time. The circuit was obtained in an English magazine (1975) is an amplifier that provides something between 1 and 2 W with good audio power. This circuit is part of a receiver, hence little key AM / CW-SSB that It can be eliminated. The reader can find the old components of this circuit on the time devices scrap and thus remove them carefully to mount a new board and use as a booster amplifier for MP3 and other modern applications. Note that the transistors used at the time are still germanium, the very popular AC series at the time. Use a power source because consumption is somewhat high for battery.
