Valve Amplifier Study 022: Quad II Vintage British Hi-Fi Amplifier

This is our proudest video to date covering the Quad II British Valve Amplifier dating from the 1950’s. We have done quite a thorough job here describing the circuit and essential work and observations to carry out before powering up after being in storage for some time. Our next video will cover the Quad Control 22 Pre Amplifier which goes with this unit. Further Updates: We will come back to this circuit design in the future when we cover basic theory in much greater detail and will include this in our Interactive Online Quiz. Our Studio Technician will also have a lot to say about this unit as well as the mic pre-amp stage.
