QUAD Vaccume Tube Amplifier Systems - Manual (Page 3)

II-forty
THE QUAD II-FORTY valve amplifier is not only one of
the finest sounding valve power amplifiers available
today, it is an aesthetic and engineering masterpiece.
An understated elegance lies beneath the smooth curves
and lustrous finish, for the power amplifiers use a circuit
dating back over fifty years to the time when vacuum
tubes ruled the electronics industry and Peter Walker
was the master of audiophile design.
He often shunned traditional thinking, preferring to go
his own way, relying on excellence in circuit design.
Circuits that are still admired today by the finest minds
in electronics for their stunning performance and, by
today’s standards, simplicity.
