RKV MARK 3 ultra highend headphone tube amplifier
___________________
The excellent results the headphone amplifier RKV MARK 3 provides, are not only based on the
sophisticated design of the circuit board.
A perfect developed circuit design is only perfect when it is implemented in accordance with the
practice.
For all these products AudioValve theoretical and practical symboise is harmonious and coherent.
This leads to a matchless musical reproduction of all sound sources.
Also in RKV Mark 3 is a fully automatic biasing servo controller to use. In our new approach we have
chosen a OPA134.
The black jack at the upper right of the backside is the IEC power inlet. Inside the power inlet a fuse can
be found as a protection against overload.
For the 117 V version the value of the fuse should be 3,15 Ampere Slow.
For the 235 V version the fuse is 1,6 Ampere Slow.
Please only change the fuse with the power-cord disconnected and if you're sure that the amplifier is not
defective!
