Qualiton X200 Gets a Major Update

Our popular X200 integrated amplifier just keeps getting better and better, as it now receives the latest version of our sophisticated  Automatic Bias Control System introduced in the P200 earlier this year.

This circuit continuously monitors the behavior of each tube and regulates the bias voltages accordingly, ensuring the smallest possible output voltage noise while guaranteeing the highest degree of linearity of the output stage. It also prevents the sensitive, high permeability transformer cores from saturating by precisely equalizing the quiescent currents of the power tubes. Finally, the bias system has a built-in soft-start function too, which prevents the tubes from drawing excessive current during start-up and eliminates pops and noises during power-up. The above means that no further adjustment is required once the electron tubes supplied with the unit have been installed, the circuit automatically takes care of everything.

The updated devices are now available to order from our authorized distributors and dealers (LINK).
