Dynaco Model 300 300W Vintage Stereo 2/4ch Power Amplifier - Bridged to 2 channels


The Dynaco Model 300 amplifier is a basic two / four channel power amplifier employing all silicon semiconductors, including 52 transistors, and 40 diodes.

This Dynaco Model 300 is in good condition, and has been bridged to work in 2-channel configuration, giving 150W per channel. This is the version without VU meters.
The smoked plexiglass cover has been cracked. Includes operation and assembly manuals.

The output circuitry is of the fully complementary symmetry design. The entire amplifier, except for an input network, is direct coupled. It's measured distortion levels approach the threshold of the most exacting laboratory test equipment, not only at the commonly specified full power ratings, but more importantly at very low power outputs as well.

This is the result of circuit techniques which eliminate any discernible crossover notch at low levels, and contributes to the QSA-300's freedom from listening fatigue. It's accurate, uncoloured sonics have been achieved on a wide variety of loudspeaker loads, including electrostatics and multiple drivers with complex crossovers.
