  • A stereo pre-amplifier intended for use with (and powered by) the Sugden A51 Power
    Amplifier     or the Sugden P51 Power Amplifier.

    Specification (all levels quoted ±1dB unless otherwise stated).
    Rated output to Power Amplifier: 600 mV
    Maximum output: 1.5V
    Output to Tape Recorder: 150 mV from disc input correctly loaded, direct connection radio and auxiliary.
    Input sensitivities and Impedances (for maximum output when driven into A51)
      Magnetic cartridge 2.5 mV into 68K equalised to R.I.A.A.
      Ceramic cartridge through plug in input adaptor to special input.
      Special 250µV basic. Supplied equalised to R.I.A.A. sensitivity 2.5mV into 68K (can be equalised to suit special requirements).
      Radio, Tape, Aux 150 mV into 250K flat response.
    THD (at 1kHz):   Aux. disc, also disc with 20dB (10x) overload with
    appropriate setting of volume control—better than 0.1%
    (mainly second harmonic) at rated output (0.25% at 1.5V output)
    Frequency Response (relative to 1 kHz, (flat or relative to R.I.A.A. as appropriate) ±0.5 dB, 30Hz - 20kHz
    Signal to noise ratio (30 phon weighting) Magnetic cartridge input better than 75 dB.
    Interchannel crosstalk typically 40dB 20Hz - 10kHz, dependent upon input load
    Push buttons to select:  
    Inputs DISC-RADIO-AUXILIARY-SPECIAL-TAPE
    Rumble Filter: 12 dB per octave below 30 Hz.
    High frequency filter Out. 4 kHz. 7 kHz. 10 kHz.
    H.F. Filter Slope: Gradual 6dB per octave, Steep 18dB per octave.
    Function: Mono, Stereo, Input Left, Input Right.
    Quiet: 16dB at 1kHz, response corrected according to equal loudness curve.
    Power: 16 volts at 13mA obtained from A51 or P51 Power Amplifier.
