    Default DCB1 TURBO BUILD @600Ma

    Hi All

    I'm in the middle of building my Dcb1turbo, I built my first earlier this year and had it finished by Alan ( Firebottle )
    It turned out to be a very good preamp indeed, I then sold this project to Macca on this forum only because Id like to push my next
    build and make a few changes, these will be listed along with pictures as i progress with the build.

    The Kit used
    Bare DCB1 turbo board by Salas rev 3.3 imported from America.
    1 X Build kit to start the project
    Elma 2 pole 6 way selector switch
    Khozmo 50k series attenuator
    Audio Note Tantalum resistors
    Nichicon caps and Dale 1% resistors throughout the build

    Khozmo Attenuator

    The Kit


    The Hypnotize turbo board

    Board Partially stuffed
    [IMG][/IMG]

    Almost complete. Im still unsure if I will run this board at 600Ma or 1.2A so have left the 2x47ohm resistors un -fitted
    along with the Fets. At 600Ma the Aluminium base will be the heatsink but at over an amp will need some serious cooling.

    Notice the 8 resistors around the relay, they have now been changed to Audio Note Tantalum.

    Will update the post as i progress with the build.

    The Aluminium Case arrives tomorrow along with some huge heatsinks
    then i can start putting my preamp together.

    Hi Oliver

    Feel free to add to the post as I know your building a DCB! too.

    Arriving today Full Aluminium Case

    Steve,

    I'd love to have something to add!!!! All the chassis and ridings are just leaving China and the Toriody tx and Khozmo are winging their way to me as we speak.

    I've managed to nearly finish the board but I've concentrated on finishing the Bigbottle.

    Now that's done, I will finish the DCB1 board. I have a suspicion I can run this board at 1.2A with the chassis I bought. Gonna have to check kind you.

    Anyway, a pic of my Hot Rod DCB1 board.

    I'm missing mine badly. Have the Chinese relay volume control but it doesn't have the Organic ability of the DCB1.

    The new one is going to be superb I'm sure. The level of components is as good as possible so I'm expecting big things.
