NEW Nichicon and Elna highest audio quality caps, Cornell Dubilier Mica caps, High precision DALE emitter resistors on the power output, updated circuitry on the power rails for better frequency response, updated driver board with high quality capacitors, resistors with matched input transistors on the front-end for best sound and updated RCA binding posts.
    Maximum Output measured 45.72Vrms or 260W each channel @8ohms.-  see oscilloscope pictures
    3.3VDC to 24VDC Remote Trigger Power Control.  3.5mm input Jack to send Remote On/Off signal.
    Soft-Start circuitry; Amplifier will slowly charge-up the 4 impressive size caps for both channels thru a 50W limiting resistor, before actuating a relay to complete the path to power-up the whole system. Soft-Start Kit obtained from Hoppe's Brain. Great site for ADCOM upgrades and info.

    Amplifier has the clearest sound and best bass response I have ever encountered.
    The outer case does show some scratches throughout. Front panel has a small deep scratch on the top front panel (Please see pictures).
    Amplifier was tested to factory specs and used for several weeks as main amplifier.
