  • Partridge 12w. P.A. Amplifier Design.

    The object of this design is to provide a high-quality portable amplifier with negligible background noise, making it suitable for high-quality work in small rooms as well as for the usual small hall and outdoor work. The special points of interest are:-

    • 12 watts undistorted output
    • Independent Control and mixing for two microphones and a pick-up
    • Sufficient amplification to give a good range with carbon microphonics and close range with moving coil microphones without the need for a pre-amplifier.
    • High-quality push-pull (Class A) output giving a level response from 30 to 15,000 cycles.
    • Special output transformer enables the exact matching of any number of similar speakers from one to any number of similar speakers
