    I am looking for a cct for a simple preamp running off 12VDC to boost
    the o/p of my phono cartridge so that it can be used as a line-in
    source on the s/c of my PC. I have a large lot of vynil records that I
    am going to burn to CD.

    Also needs RIAA equalisation.

    How deep are the OPs pockets?

    ** Is it beyond the comprehension of a sheep shagger to use the "rec out"
    signals from the stereo amplifier that goes with that phono system ??

    Wes Components sell the SP-24A phono preamp. It comes in a shielded
    box and includes a power pack. IIRC, the price was $30 to the trade.

    Otherwise there was a kit designed by Silicon Chip magazine. It
    doesn't run off 12VDC, though.

  7. top post, flame expected. see below.

    //crap snipped

    Is it beyond your comprehensive facility to understand that the OP has a
    turntable, that needs both preamp and riaa equalising.

    Do you personally have ANY experience with de-clicking, de-popping and
    rejoining treasured, irreplaceable vinyls?

    Your total value input to the the thread has been NULL, as usual.

    Do you just lurk here for fun and profit?

    jo770. there are lots of preamps around. Cheapest case, do as electricile
    above suggested, plug turntable into an amp with phono inputs, then use the
    tape loop on the amp to connect to your soundcard.

    You'll also need some software, I like Soundforge, others like DiamondCut.

    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:

    ** Nothing was snipped.

    Much crap was added.

    ** Precisely what the phono stage of a stereo amp does - you fucking

    Seeing as the dumbfuck OP has a phono cartridge and lots of LPs - he just
    might be expected to have a turntable and a stereo amp as well.

    ** Do you have any personal experience of sheep shagging ??

    Any other farmyard animals you prefer ?

    ** Shame anencephalia prevented you seeing the point of my question.

    ** Now the colossal, asinine fuckwit re-posts my question as his suggestion

    Polly wanna cracker ???

  10. Recursivly, unfortunately,

    The OP may not know how to rip them, which I believe was the question. With
    all your brilliance in impedence matching, interpesonal skills, DSP
    programming and data storage (all yet to be demonstrated) I'e sure everyone
    is convinced you may be leige lord.

    How fucking rude do you want to be:) This's great exercise, and I suppose
    bandwidth's cheap enough to allow it.

    Cooked, eaten for dinner.

    OK ya got me there, I had to look that one up.
