This Adcom GFA-1 stereo power amplifier is a heavy & high powered component, weighing 26lbs, producing 200W RMS per channel @ 8Ω, & 340W RMS per channel @ 4Ω. ...but it isn't just about power, as this amplifier produces a beautifully clean sound. This power amplifier is ready to be connected to even the hardest to drive speakers.
The interior of the amplifier has been cleaned (chassis, boards, heat sink, fan blades...). Inputs & outputs have been cleaned with Deoxit. The exterior has been detailed. This amp has been fully tested & everything works properly. Ready to plug & play
A demonstration can be arranged for serious buyers.
From a clean, smoke-free, & pet-free home.
