    Can anyone help with deriving a 12v DC supply from a transformer that's
    giving me 12v AC at the moment please.

    I extracted this transformer from an old telephone system (must have had a
    rectifier (is it?) in the system but I didn't realise I'd have to remove
    that too). I want to try running a car radio/cassette from it.

    Thanks.

    A full wave rectifier will do the job though you will loose a little opacity

    I would also check the current raiting of the transformer.
    A lot of the newer high power car units can draw >10 amps.

    A bridge rectifier, a capacitor and a regulator....the specifics would be
    dependant on further info...good luck, Ross
