ATA-134


ATA-134 is our stereo tube amplifier, which employs EL34 tubes working in triode mode. The amplifier operates in Class AB without using negative feedback. ATA-134 was designed from the ground up and benefits from the use of custom made transformers designed and manufactured by AUDES including separate filament and High Tension anode toroidal core types with precise winding sectioning and low primary current. Special split tape wound core output transformers, which employ thin high quality steel, were developed specifically for ATA-100 tube amplifier series. Only high quality selected components are used: all resistors are carbon film and audio circuit capacitors are of PIO (paper in oil) type produced by JENSEN.


ATA-234R


ATA-234R is our stereo tube amplifier combining powerful sound, excellent reliability and ease of use by utilising push-pull class AB ultra-linear circuitry and automatic biasing. ATA-234R was designed from the ground up and benefits from the use of custom made transformers designed and manufactured by AUDES including separate filament and High Tension anode toroidal core types with precise winding sectioning and low primary current. Special flat-type UI core output transformers were developed specifically for ATA-200 tube amplifier series. Only high quality selected components are used: all resistors are carbon film and audio circuit capacitors are of PIO (paper in oil) type.


ATA-288R


ATA-288R is our stereo tube amplifier combining refined Class A sound and robust output power by utilising push-pull class A ultra-linear circuitry and automatic biasing in a dual mono configuration. Class A operation keeps distortion low and provides for a natural highly enjoyable sound with an abundance of detail. ATA-288R was designed from the ground up and benefits from the use of custom made transformers designed and manufactured by AUDES including special flat-type UI core output transformers developed for ATA-200 tube amplifier series. Only high quality selected components are used: all resistors are carbon film and audio circuit capacitors are of PIO (paper in oil) type.
