Adcom GFA-555 (Pro Version 1)

200WPC High Current Stereo Power Amplifier w/ Rack Handles


Front panel is in nice condition, top and sides have seen some wear - though not an issue if you intend to rack it! This unit still rocks! Original box, packing and manual are not included.

At 200 watts per channel, this solid state amp from the 80's offers exceptional value and superior performance at a reasonable price. Great for low impedance loads. The GFA-555 is of the smoothest, quietest, and nicest-performing amplifiers we have seen over the years.
