Quad 33 Pre Amplifier

Quad products have always displayed a certain originality in their design, and here we have an example of this in the Quad 33 pre amplifier. It is now in fully working condition after the pots and switches have been cleaned and the suppression cap was replaced. However, cosmetically it is showing signs of its age – please refer to photographs. The unit will come professionally packaged, with dedicated cable and our regular 3 month warranty.
Quad Say….
The Quad 33 is the control unit of the system. Mounted in a convenient, accessible position, it selects and controls the radio tuners, gramophone pickup and tape recorder connected to it and feed the loudspeakers via the power amplifier, providing for stereo, or mono on either or both channels, from all inputs, plus monitoring and track selection facilities for tape.
The controls are comprehensive but simple and are logically grouped to facilitate selection and control of the programme.
The filter is essential with modern good quality speakers and helpful at any time. It removes surface noise, tracing distortion and similar shortcomings in the upper frequency range of the recording or broadcast, and the two control filter system achieves this to a very fine degree without intruding unnecessarily into the harmonic range so essential for realistic reproduction.
Another, fixed, built-in filter cuts out (without affecting the normal low frequency response of the equipment) unwanted signals at frequencies below 20 Hz, due to mechanical causes in motors and turntable mechanisms.
Entirely separate from the filters are the bass and treble controls which provide independent adjustment of tonal balance when required. Their operation is symmetrical and smooth without any unpleasant “steps” in the response.
