Eelvõimendi-lamp Quad QC 24

QC Twenty Four
For the QC Twenty Four pre amp, our designer scoured the globe for the very finest components, with possibly the best example of this being the new 'old stock' 6111WA double triode.

With transformers designed by one of the world's leading authorities and relay input switching the musical signal is preserved in its purest form - pursuant to the philosophy of the theoretical perfect amplifier which Peter Walker himself stated is, 'a straight wire with gain'. The QC Twenty Four has 2 main outputs, 2 Tape Play and Record connections and inputs for CD, Tuner, Aux 1, Aux 2 and an optional Phono port.

Inside, the QC-Twenty Four is claimed to use a "radically new and functionally simple audio circuit and features relay input switching to preserve signal purity".
Tube complement is a single tiny6111WA twin triode said to have a life of 60,000 hours. Quad specifies a frequency response of 5 Hz-50 Hz (+0 dB/-0.5 dB), hum and noise >80dB and recommends a minimum load of 50KOhms

The Quad QC-24 is dedicated valve phono stage preamplifier. It has been designed for Quad by valve supremo Tim DeParavicini , probably the finest valve amplifier designer in the world today. It has been voiced by the finest ears in the industry and will add an entirely new dimension to enjoyment of vinyl recordings. This unit features a moving magnet/ moving coil toggle switch on the rear, a choice of input sensitivities and a direct full level output or variable level output if you wish to connect directly to a power amplifier.
