The AU-555 is a very well regarded amplifier in the audio community. Popular for its sweet sound and more than sufficient power to drive large floorstanding speakers. These units are built to last and this particular one is in its all original glory. The cover got the original paint and the fascia does not have the slightest scratch.
We have cleaned the insides of the units from dust, replaced the broken bulb for the power light and doexidised all knobs and potentiometers. Also the noisy 2sc871 transistors have been replaced with superior new ones making this great amplifier perform even better.
This unit comes with 3 months warranty.
