    I have a Minolta XE-1. I would like to use a Vivitar 2800 with it. I
    have been told that high trigger voltage can dammage some (newer-?)
    cameras. I have seen quoted the 2800 has around 140V trigger, but mine
    (and sevberal others I know of (possibly newer ones???))measures only

    Will this be OK for a circa 1977 camera?

    Is anyone using this combo?
    Does anyone know the contact specs for the XE?

    At only 20 volts, you'll be fine.

    20 volts can supposedly damage Canon EOS cameras, but I hear that most Nikon
    and Minolta cameras are designed to handle up to 250volts (but I wouldn't
    recommend it). I was using an Acheiver flash, which I measured at 260
    volts, on my X-700 before I realized what I was doing. I've since upgraded
    my flash to something newer and better (with a lower trigger voltage).

    Yes. Older cameras mechanically trigger attached flash units and are
    not affected by those high voltages.

    All Minolta cameras up to and including the first AF (Maxxum)
    generation---i. e. 5000AF, 7000AF, and 9000AF---will do fine
    with any flash trigger voltage.

    The Minolta SLR cameras that cannot withstand higher trigger
    voltages are those with the new proprietary hot shoe---i. e. the
    'i' series and later.

    This is what a Minolta technician told me.

    With many flash models, the trigger voltage has been reduced
    during their production time. So earlier samples may have high
    trigger voltages of 100 V to 600 V; later samples of the very
    same model may have lower trigger voltages of 24 V or less ...
    as instruction manuals always say: "Technical specifications
    subject to change without notice."

    The Minolta flash shoe is *not* a hot shoe. It is, as you say, their
    proprietary flash shoe, not merely a trigger.

    The Maxxum 9 and 7 will take any PC sync voltage and polarity on the PC
    sync connector.
