Quad 33 Pre Amplifier

The Quad 33 preamplifier is a significant piece of British audio heritage, originally released in 1967. Designed by Peter Walker, it was intended to complement Quad's renowned electrostatic loudspeakers. Its compact, half-width casing and striking grey and orange aesthetic made it stand out, and its versatile tone filtering offered a high degree of user control.

This unit features a distinctive control layout, with bright orange push-buttons and rotary controls for volume, balance, and specialised high-frequency filtering. Connectivity is handled exclusively via 5-pin DIN sockets, reflecting the era of its design. Internally, the Quad 33 utilises modular circuit boards, allowing for customisation, notably with an adaptable card for phono and tape inputs.

This vintage preamplifier is a highly regarded component for those seeking classic British sound. Its modular design and unique filtering system contribute to its enduring appeal among audiophiles and collectors.
