DESCRIPTION

Overview

The Qualiton 300B is an integrated stereo amplifier with 2 × 25 watts of output power, built around the sound character of 300B power tubes. It blends Qualiton’s classic heritage with modern details, using refined vacuum tube circuits enhanced with additional functionality. Qualiton’s stated goal with this design was to move away from the pronounced coloration often associated with 300B tube amplifiers, creating a smooth, musical, and balanced vacuum tube amplifier across the audio frequency range.

Design & Engineering

Qualiton’s approach to tube amplifier design emphasizes loudspeaker compatibility, low noise, fast and controlled transients, wide and flat frequency response, robust technical parameters, and sound quality. In the 300B, the 12AX7 and 12AT7 tubes are used in the preamplifier and driver sections, supported by DC-stabilized filament supply and circuits with low offset and stable DC operating points.
