A fine old quad 33 Preamplifier with built in moving magnet phono stage. This is working producing a good clean sound through all inputs. All the front controls work quietly and with smooth action. No loud pops when you switch on as is common on this unit. The front illuminated sign comes on sometime and sometime it does not. The back is fine with no cracks to the rear panel. All the slide in boards are present. Comes with a mains lead and an DIN interconnect cable to attach to the partner Quad 303 power amplifier. This is not the standard Quad cable but a Monster cable upgrade but the DIN plugs on this cable are not as secure as the factory originals so make sure you push them in fully. The tape replay DIN socket has been pressed in too far but is still attached to the rear panel. In average cosmetic condition with rub marks on the volume knob and light rubs the case but no heavy scratches or dent to the case. We have the matching Quad 303 power amplifier for sale Will be well packed for delivery.

Classic Quad 33 preamplifier with power and output cable. Tested for power and basic function. Plug in to tape input and played fine without any audible distortion or scratching with the controls. Power indicator lamp is working. The internals look clean, complete, and free of corrosion. The service history is unknown so could likely benefit from service. It has been switched to 120V for use in the US (may be switched back to 220V if required) Aesthetically, the preamp is imperfect. It looks like the face was repainted with a matching paint at some point, but there are flaws to the surface with some spots wearing through the paint. Im including a new volume knob to replace the worn original one. None of the visual flaws affects the functionality.
