Belles 22A Preamplifier

The performance and engineering found in the Belles 22A is typically reserved for higher priced components. Internally the 22A utilises a hybrid vacuum tube design.

The unit uses two 12AU7 valves in conjunction with power mosfet regulators. Also providing isolation from the power supply, which in turn greatly improves the stereo imaging.

Description

Distortion on the Belles A22 is extremely low, which brings out the dynamics and detail, within the music. The emitter follower output is biased with a constant current source instead of a resistor.

Belles 22A pre amplifier has been designed to remove variances in vacuum tube behaviour due to manufacturing indifferences and tube aging.

Externally the Belles A22 is visually a work of art. The entire chassis is made of brushed anodised aluminium. The front panel is 38mm thick, machined and engraved, come in either Black or Silver

The 22A is one of the most outstanding value for money pieces that power modules have produced.
