    to all,

    I have been good friendship with huang yong.as a diyer,I am glad to help forward diy stuffs.

    I have supply huang yong audio parts as a technical adviser.we share information.But with more and more intercourse,I find he is going to diy for no good incentive.so I decide to stop my supply.

    the truth is I have send this guy 12PCBs zen boards,5PCBs Mj boards,2PCBs SOHA and lots of audio parts,lots of design ideas as free!the pay back is his affront!!!!

     

    I HAVE NOTHING TO SAY NOW.YONG CHAO!WE FRIENDSHIP IS OVER!!!!!!!!!

     

    ----------------------------------------------------------------

    to heady and others group buyer of SHOA

    all SOHA boards was delivered to Edwin 2006.8.

    the buffer have part refunds and few assemblied shipped to Edwin 2006.10.

    if someone still not receive it,please contact me private.

     

    thanks all

    Just finished my SOHA today but have not case it yet, in fact have not found a case I like yet. Like to ask the experts about my built:

     

    The voltages for most of the test-points seems to be ok, except the -12.6V, which is actually only -12.47V.

     

    B+ = 54.7V

    V+ = 11.98V

    V- = -12.06V

    heater = -12.47

    All the resistors values are as per the BOM. Any problems with these readings? Thanks.

     

    these reading is ok.

     

    have you short the output resistors?what cans are you listening?

     

    nice building!

    digi,

    can you give us a parts list for your PCB, including the parts list for the diamond buffer? Which parts on the PCB are replaced by the buffer? I'm afraid of buying extra components.

    was reading on the headwize website and it seems like there are many variations to the CCS. I don't understand the technicalities, but which part is your PCB using? Is it fixed? Any recommendations for noobs?

    Thanks

     

    here u go LINK.

     

    the buffer is in progress,its only assemblied unit available.

     

    good luck!
