  • A hi-fi stereo integrated amplifier with class A/B output power of 20 watts RMS per channel into 8 ohm or 25 watts RMS per channel into 4 ohm. Inputs for phono, radio, aux and tape. Terminals for 1 pair of loudspeakers, jack for headphones.

    SPECIFICATION (all levels quoted ± 1dB)
    Power output: 20 watts RMS per channel both channels driven
    at clipping level into 8Ω loads or 25 watts into 4Ω loads.
    THD less than 0.1%, mainly 2nd & 3rd harmonic, negligible proportion of high order harmonics and reducing in proportion with reducing power.
    Frequency and power response ±1dB 30Hz to 20KHz.
    Output to tape recorder direct connection from radio and aux. inputs, 200mV from disc amplifier when correctly loaded at average modulation.
    Input sensitivity:  
      Radio, Tape, Aux 100mV into 200kΩ flat response
      Magnetic Cartridge 2.5mV into 47kΩ, equalized to R.I.A.A.
      Ceramic Cartridge 50mV into special input circuit.
    Signal to noise ratio       (30 phon weighting) 80dB on radio, aux. and tape inputs.                                   70dB on disc inputs
    Interchannel crosstalk typically 40dB 20Hz - 10KHz, dependent upon input load impedance
    Rumble Filter Built in on disc input, 18dB per octave below 30Hz.
    Push buttons to select:  
      Inputs DISC, RADIO, AUXILIARY, TAPE.
      High frequency filter 12dB per octave above 7KHz.
      Function Mono, Stereo, Input Right, Input Left.
