    Altec 771B Plate amp

    Need your help again guys. Are these reasonable? He clearly states these are the SS type. Today that's around 315USD.

    Altec 771b 1970's plate amps-60+30 watts+adjust.3 point x-over switch.
    Nothing like a great big pair of speakers to make your day.

    They are awful.

    Blow up, don't sound all that great and he wants about triple top dollar.

    OK, but what do you really think about them? Don't pull your punches, let me know.

    Thank you OG, you saved me some bucks for those 604's I look at tomorrow.

    Cheers.

    In the last couple years there have been about 20 posted to Fleabay, of which 18 were non functional.

    The 771A sounds better, but blows up worse.

    The B doesn't sound good and still blows up.

    OTOH the rack mount Altec biamps are nice.

    Yes, that's the one.:2thumbsup:

    Sadly, not exactly the ideal "onboard" unit for a speaker box. But IMO, has the reliability and sound worthy of the big "A" and green paint.

    Re: Altec 771B Plate amp

    Just to add to OG's comments, My 9846's were originally the B model with the
    771's installed in an auditorium. After the embarrassment of multiple in-service failures,
    the 771's got tossed into a dumpster. With great external bi-amp setups available, why
    bother with these at all...........

    Before Tripath went south I was gonna play with putting their chips in the 771 frame, but alas.

    This late in the game best just forget it.

    "ALTEC has combined the 711B Electronic Crossover Biamplifier with the 1204B Portable Nonpowered."

    Typo by Altec, it's 771B
