  • Excellent, small and powerful amplifier

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    Stereo single-ended configuration
    Po output power RL = 3 ?; THD = 10 %; VP = ±27 V - 110 W; RL = 4 ?; THD = 10 %; VP = ±27 V - 86 W
    Mono bridge-tied load configuration
    Po output power RL = 6 ?; THD = 10 %; VP = ±27 V - 210 - W

    Cons:

    It comes with output filter inductivity of 22 mH and capacitator of 470 nF.
    Those results in engaging of the low load impedance protection at high power on RL = 4 ? .

    OtherThoughts:

    The output filter values in Stereo single ended mode should be:
    RL L C
    2 ? 10 mH 1 mF
    4 ? 22 mH 680 nF
    6 ? 33 mH 470 nF
    8 ? 47 mH 330 nF

    Bottomline:

    Perfect small amplifier with a reasonable price
