  3. Group Buy for KG's Boards (2nd)

    in Do It Yourself

    Posted · Edited by Lil Knight

    Hi Pal,

     

    Overkill is a standard here so everything will be balanced, if possible.

     

    The quantity in the spreadsheet is for set which already includes amp boards and PSU board, not the number of single boards, so please take note of that.

    Extra Requirement column is used just in case you want something extra or for backup.

     

    The KSA5 and Squarewave share the same PSU which is either original or alternative. Choose what you want.

     

    KGSSHV = 2x amp boards (either mini onboard or standard offboard) + 1x mini PSU.

    Squarewave = 4x amp boards (each board is single channel) + 2x KSA5 psu (either original or alternative, just note what you want).

    Dynahi onboard = 2x amp boards for balanced. Use the Sigma22 for PSU.

    KSA5 = 1x amp + 1x PSU. Since the board is huge, it's stereo only. Putting the quantity = 2 if you really want it balanced.

    Megatron = 1x amp for now. I will see if I could add the PSU for it. If not, the KGSSHV PSU will be included.

     

    From what I see from the spreadsheet, eggil seems to be confused about the extra requirement :) The PSUs are already included in the set.

    Nebby and holland might be confused about the number of sets.

     

    Cheers

    I've got the permission from Dr Gilmore for a second run of boards, so let's do it again. :)

     

    Linky to the spreadsheet: https://docs.google.com/spreadsheet/ccc?key=0AoNVeoQi85GgdFVrMmtReVpWNVBsQUo2Sl9iSkItM2c#gid=0

     

    Please take a look at the notes before putting your needed quantity.

     

    If you want something extra (like a single PSU or amp), just put a note under Extra Requirement column.

     

    The Megatron is not fully-tested so if you really want to try it, do it at your own risk. :)

     

    Silkscreens for the boards:

    I will let the GB go for 2-3 weeks and then go ahead ordering for boards. Probably another 3 weeks for fabricating. Shipping time right after.

    Feel free to let me know if I miss something.

     

    Cheers.

    Very nice Tran. How many builds this year so far?

    I have 1 DAC, 3 dynamic amps and 3 electrostats.... but nothing totally finished. :(

     

    Hi Tran,

    What is the size of your bottom plate?

    It's 215mm x 300mm. :) Might hard to squeeze in a large pot like the Khozmo or RK50, but something like the DACT or Alpha would be just fine.

    I don't think the BH will ever be released to public. :) But the Megatron is very tempting indeed.... Other boards I'd love to try or prototype are the onboard Dynahi, KSA5 and Dynalo.

     

    I've just stopped by the machine shop to pick up my custom case for this KGSSHV. Haven't finished the front panels, but here is the bottom plate. Very compact and the PSU and amp are the same size :) A stack of them would be awesome, I hope.

    Good job all round gentlemen. Will you make the pcb available to us now?

    As usual, gerber file to make boards is available from Dr Gilmore. Just ask nicely. :)

     

    Just wondering if you managed to test it out with the amp boards, yet. Wondering if there are any sonic differences from the older sand to take note of? 

    I am waiting for the peek screws to test with the new mini amp boards which use all new devices. When everything is done, I will try to compare with my old KGSSHV. Sonic differences... might be yes, but very small, I guess. The main advantage is everything can be sourced from a single vendor which is a huge plus. Mouser now has the 2.5" Aavid heatsinks so we don't have to order them from Digikey. I compared the Aavid with the 2.5" Ohmite in my BOM and the former is a clear winner.

     

     

    Group buy will be opened in a day or two. Thinking of what other boards should we order? :)
