Quad - 405 (ensemble: amplifier 405, preamp 33, FM3 tuner) Audio amplifier - Multiple models

Superb Quad set consisting of a Quad 33 preamplifier, a Quad 405 power amplifier, and a Quad Fm3 tuner.

This legendary British brand from the great era of hi-fi in the seventies needs no introduction!

The Quad 405 is a two-channel power amplifier designed for domestic and professional use, utilizing a current discharge technique that eliminates many transistor-related issues.
This unit has been refurbished and fully recapped with high-quality audio components. It now also features RCA sockets and speaker terminals that accept larger diameter speaker cables. It operates perfectly without any transformer noise.

Output power: 100 watts per channel at 8 Ω (stereo)
Frequency response: 20 Hz to 20 kHz
Total harmonic distortion: 0.05%
Input sensitivity: 0.5 V
Signal-to-noise ratio: 95 dB
Speaker load impedance: 4 Ω to 16 Ω
Dimensions: 115 x 340.5 x 195 mm
Weight: 9 kg

The Quad 33 selects and controls radio tuners, the record player reading block, and the connected tape recorder, and powers the speakers through the power amplifier, offering stereo output, mono on either channel or both, from all inputs, as well as monitoring and track selection functions for the tape. The controls are comprehensive yet simple and logically grouped to facilitate program selection and control.
The filter is indispensable with modern, high-quality speakers and useful in all circumstances.
It eliminates surface noise, trace distortion, and other similar defects in the higher frequency range of recording or broadcasting, and the two-command filter system achieves this with great precision without unnecessarily encroaching on the harmonic range that is essential for realistic reproduction.
This unit has been recapped and inspected, and it works perfectly.
