The Audes ATA-288R is a stereo valve amplifier combining a 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. The Class A operation keeps distortion low and provides for a natural highly enjoyable sound with an abundance of detail. ATA-288R was designed from scratch and benefits from the use of custom-made transformers designed and manufactured by Audes, including special flat-type UI core output transformers developed for the ATA-200 valve 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.

AUDES traces its origins to September 1935, when the first tube radio was sold under RET trademark. Between 1956 and the late 70s tube radios were manufactured under ESTONIA trademark. From 1978 until the 90s only transistor electronics was in production. The end of the 20th century brought the revival of tube audio. In 2001 AUDES designed and manufactured a high-end tube amplifier NS-S, which incorporated the best available components and technologies of that time.

The ATA-200 series amplifiers employ special NS circuit topology developed by AUDES. Components used throughout the amplifiers are selected as ‘best for the application’. AUDES designs and manufacturers its own toroidal core power transformers, employing precise winding and sectioning geometry and with low primary current. The heater and the plate voltages can be turned on and off independently, which extends tubes’ lifetime and allows for power saving standby mode during a pause in a listening session.

ATA-200 series amplifiers come with a remote control, which can be used to adjust the volume, as well as select one of four line inputs. Volume knob and the input selector are also to be found on the amp’s front panel. LED indication is used to display which input is currently in use. On turn-on or input change the output level is automatically reduced to safety as a protection measure.
