    Does anyone what function each pin is for on phono cards from a 52? I want to use them in a standalone stage.
    Presumeably 0v, 24v, in and out, but which pin is which.

    AKA 523 boards - will also fit any olive type large box preamp (92, 102, Nait3, 82, 52 and quite possibly the new generation as well).
    Good thinking!
    Hi David
    If you hold the card up, component side facing you, the pins are:
    Upper right - GND
    Mid-right - input
    Lower left - +24v
    Mid left - output

    Best regards, Yair
