Push–pull output
Videos
A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. This kind of amplifier can enhanc
Transformer coupled vacuum tube push-pull audio amplifier from 1924. The two triode output tubes are on right.
A Magnavox stereo tube push–pull amplifier, circa 1960, utilizes two 6BQ5 output tubes per channel. The two pairs of push-pull tubes are visible in front of the output transformers.
Typical transistor output stage of one channel of a 65 watt stereo amplifier from 1993. The 2 MOSFET push-pull output transistors (FET2, FET4) are bolted to the black heat sink. They are driven by transistors Q2, Q5, Q6, and Q7
Power amplifier classes
