    I have a roland gr33 guitar synth that runs off a 240Vac to 14Vac adapter.

    I would like to run it from a car battery.

    If it has a simple rectifer cct then as far as I can see DC into a rectifier
    just gives DC.

    I have forgotten my electronics 101


    Any help out there.

    Regards

    Only if it has a simple rectifier but if it has a floating
    supply with the output voltages above and below ground it
    will not work on just DC in.
    A small invertor from one of the electronic supply houses
    will get you out of trouble using your original adaptor.
