    Does anyone have the circuit for a "versatile preamp" . It was in EA or
    Silicon Chip some years ago. It use TL 072's , and can be set up for
    Mic, or Phono etc.
    I built a few ages ago for Mic, but now need to change it to Phono to
    rescue some old vinyl. Just needs a few component changes.
    Just bought a nice new A/V reciever, does everything, video, audio,
    more DSP than you can cope with, but no phono preamp!!

    Here is a recent design:

    It comes in two parts, the power supply and the preamp. DSE sell the
    preamp section (no transformer) for about $19:
