    KGSSHV Carbon Build Thread

    Use the STN9260. I did on my amp and it works just fine.

    2018 PCB Group Buy with TKD pots

    Just wanted to say thanks again, @sbelyo, for leading up this group buy. Probably the largest and/or most complex group buy I have seen recently on this or other forums! Let us know when you have the shipping cost calculations complete!

    grounded grid

    I had this issue with my Blue Hawaii. It was drawing more power than the GRHV was set to output. As I recall, I changed the 5R1 resistor (the large 3W one) to 2R5 or thereabouts and that solved the issue. I just soldered another 5R1 on top of the existing one and it worked fine. The 5R1 sets the amount of current that the PSU will supply.

    Revised shunt power supply for SRX Plus

    Great to hear you did not give up on the shunt PSU!! I have a SRX build that I want to use this PSU for, and I hope to build it point to point in the coming few months. Thanks, Jim!! And still loving your SRX Plus design using the current BHUltraMini PSU. Cheers!

    Thanks for the updates. These group buys put a big load on the person who organizes them, and this one was the mother of all group buys. So don't sweat it. I certainly appreciate all your efforts on pulling this buy together!

    Tube boards are best to be 2mm.

    BTW, are those EL34s Tung Sols? Edit: I see in the reflection they are Svetlana's. Great picture!

    Shunt vs. linear reg

    I know JimL designed and built a shunt PSU for the SRX-Plus. Great article on it in AudioXpress I can send you if you want.

    Given the fixed setup cost, you might want to ask @sbelyo to get a quote for 2 or 3 sets rather than just 1 set. Price will only go up marginally, and you could probably sell the others later. Or keep them in case one or two boards blow up and need to be rebuilt!

    2018 PCB Group Buy with TKD pots

    @sbelyo, Can you put me down for 1 additional pair of GRHV boards (so 3 pairs total)? And 1 additional GRLV board (3 total)? Will you be PMing everyone your paypal address for payment?

    And for Grounded Grid: Basically a Carbon with Tubes. Or others might call it a Blue Hawaii with updated design. I prefer the former description.
