    Default Big Bottle MkIII Phono stage

    Just about to start my next build, which is a MM/MC valve based phono stage, which is the brainchild of Firebottle and Bigman.
    It uses an ECC83 (or can be switched to use a Russian equivalent) and two PCC88s.

    I have finished shopping for the bits today, so I am just waiting for them to arrive from various parts around the world.

    I will update this thread with progress as I go along.

    I have to agree with Karl. I'm so glad I built one of these.

    So far, I am missing the case, and the 6M8 1% resistors.
    Apart from that, I spent a few hours populating the board today.
    Oliver kindly sent me some matched resistors and capacitors for the RIAA.

    I am looking forward to finishing this, but need to be patient.

    Awesome , I was going to say make sure you take care to ultra match everything as it makes a real difference.

    The 6M8 don't need to be that accurate or matched as they are only used for biasing.
    I love Hendrix for so many reasons. He was so much more than just a blues guitarist - he played damn well any kind of guitar he wanted. In fact I'm not sure if he even played the guitar - he played music. - Stevie Ray Vaughan

    Thanks Alan.
    I'll just take a random pair out of the bag. They should be here on Friday, so I am looking at finishing this to a point I can put it in a case over the weekend.

    The BB3 PCB is now fully populated, and powers up nicely, with the valve glow on display.
    I have modified a soft start in line with the recommendations, and prepared the 3 pairs of RCA sockets ready to fit in the case.

    I just need the case....
    It is in France now, but not yet at my house.
    I am hoping I can finish this by the end of the weekend.
