    some have circuitry to protect against this, but many don't . . .

    my reason for the inquiry --
    how many auction (o.k., eBay) listings have you seen where a "powerseller" / pawnshop says that the poweramp powers up, but they don't know if it works otherwise - and item is sold "as is"

    with a speaker cable / binding posts connected but no cab - that would be very bad,
    but what if a poweramp is turned on with nothing attached ... bad ?

    AFAIK, it is only a problem with Valve/Tube poweramps and not with solid state poweramps.
