    The problem doesn't tend to manifest itself when the above mentioned precautions are taken.

    The caps seem to act as a bridge to accomodate the short path when in contact with the pcb.

    It does look like that the +/- traces are way too close together to handle these high voltages.

    Hopefully the new "mini" boards will be an improvement.

    So I'm trying to track down some buzz/hum I'm getting in just the left channel of my recently acquired HV. The level of the buzz doesn't change with volume level at all. Here is a diagram of the grounds in the amp

    The wire connecting the power supply to the star ground goes around behind the transformer, and when I move that wire around the buzzing changes, but it is weird that its only buzzing in the left channel during all of this.

     

    Also of note is that this is my first/only stat amp, and I only have one brand new pair of Stax, 307s, that got to me from Price Japan with a channel imbalance issue. So I can't test other amps/cans.

     

    Any advice is appreciated guys :D

     

    Run a search in this thread for "star ground". It has been discussed at length.

    My KGSSHV has zero discernable noise, never did. It just blows up all of the time.

    Another common theme with this amp. I hope your trafo is robust enough

    and that the large HV lytics on the PSU are stood-off or insulated with kapton tape!

    Turns out Drew wants to send Kevin a used unit from the Cali show.  What a fucktard and he's even going to charge full price. 

     

    The were not used (then). They were stuck in customs at that time.

     

    EDIT: I was referring to the recent 7/20/13 Cali meet. 

     

    There were two other recent Cali meets. One near Los Angeles in Newport Beach and another near San Francisco.

    None reported that the King Sound was present at those meets. They did make a showing recently at a New York meet.

    So yeah, there is a used set out there.
