    Unfortunately I have two left feet when it comes to DIY stuff. A friend who has a CNC machine built it for me.

    He did well, the finish is superb.

    So what makes a hot rod and how is a turbo different. I have a hypnotize dcb1 black pcb built by a guy on DIYAudio. I bought it off Tom. It has Riken Ohms in the 220k and 1 meg positions and the four 220r are Shinkoh. The .22uf caps are now Jupiter copper foil in paper and wax. I first checked with Salas who confirmed these are the most important areas to improve. The rest are Dale, prp and Elna.
    It has a TKD 601 pot that I am going to change to a Khozmo of similar.
    I will take some internal shots when I figure out how to post pics to this site.

    Hi Keith,

    The "Hot-Rodding" is in direct relation to how much juice you can get through the board.

    Level 1 is 60mA (standard build)
    Level 2 is 200mA (Mur860 upgrade)
    Level 3 is 600mA (Mur860, 2.7ohm resistor change, 14w heat dissipation necessary)
    Level 4 is 2A (Mur860, resistor change. Heat dissipation by fans and heat sinks)

    The difference in clarity between 60mA and 200mA was significant. I'm glad I got it done for the new owner of my old one.

    New build will explore a 1.2A version. Heat dissipation will be done via the Aluminium chassis and possibly a couple of 1" fans or similar. If that's not possible it will be 600mA

    Hi All,

    Just a bit of an update to the build with a few pics.

    Checking if the layout works !!!

    [IMG][/IMG]

    Moved the fets off the board ( Firebottle ) suggestion to disperse heat through the
    thick aluminum base and fit Khozmo Attenuator and Elma 6 way switch

    [IMG][/IMG]

    Will run at 600mA to settle in then will try at 1.2A using the huge heat-sinks for comparison

    [IMG][/IMG]

    Inputs wired using Olivers (Bigman80) Spotfire cable



    I hope to have this finished soon but will wait until my wrist feels better before wiring the power.
