    Finally got my boards as well (inexplicably long customs delay...). Much appreciate the effort from mwl and anyone else that made this GB happen //UFN

    Would you not mount the amplifier PCB with the transistors at the bottom of the heatsink? In that case, the balance pot is at the top and the standard straight pot should be OK to adjust even after the board is mounted? //UFN

    Agree. Hum could occur because of a poorly designed transformer, an undersized transformer, interference (due to suboptimal wiring), grounding issues etc. Just moving the transformer to a separate enclosure isn't guaranteed to fix the issue. //UFN

    As I recall, the recommended transformer for a non-balanced original Dynahi was 2x30V/80VA+. Each board draws around 300mA, so 80VA would be roughly twice the current draw of two channels. //UFN

    Very interesting... //UFN

    Yes, by a very long way... //UFN

    No problems. Note that the duty is supposed to be included in the EU-prices (euro or other local currency) so you only pay VAT on top (25% for me) - unless you're VAT registered of course. The VAT amount is just added to the amount deducted from your credit card at check out (although it's not visible until just before you confirm the order). I can order much later in the evening than that, but my orders are mostly small and probably don't take long to pick and pack //UFN

    Not sure exactly where you are located, but I more or less buy everything from Mouser now. Massive selection of parts and very simple ordering. I do get charged local VAT on top of their prices, but it's done immediately and there's no fiddling with customs, additional fees or delayed bills etc. afterwards. Shipping is free for orders above 65 EUR. It's via FedEx which wouldn't be my first choice, but it works well and it's a fairly consistent two-day delivery (so order on Tuesday night EU-time and delivered during Thursday or Friday at the latest). I do still use Reichelt and TME sometimes, but it is getting less and less frequent. If you are in a country where RS/Farnell is an option that could work as well, but IME prices are much higher. //UFN

    Email sent. //UFN

    I always tap by hand. Having had to fix a couple of broken taps (and discard a couple of heatsinks that couldn't be fixed) I've decided once and for all that those extra minutes to do it by hand is a good investment... //UFN

    Will you send out requests for the shipping costs? I think a separate Carbon build thread is a good idea. //UFN

    Absolutely gorgeous! //UFN
  13. UFN
    Great. Hope my boards are among the ones that are ready to go //UFN
  14. UFN
    Nice idea, I may want to copy that //UFN

    Saw them as well - and immediately started dreaming up around 57 potential ways to violate Schist's advice of "Do not use these in other products" //UFN

    Paid. //UFN
  17. UFN
    No objections your honor //UFN

    Happy with mine as well. //UFN
  19. UFN
    Looks really good to me //UFN

    My guess would be that it is due to the volumes they order from the supplier, but I am not sure. I have also seen some cases where the 50ppm RN60s cost less than the 100ppm ones of the same value so there are some inconsistencies here and there //UFN
  21. UFN
    Fully agree! //UFN
  22. UFN
    Isn't that just showing the difference between the "civilian" and the "mil-spec" ratings? //UFN
  23. UFN
    +1 on this //UFN
  24. UFN
    Updated my entry on the spreadsheet, thanks a lot to MWL and soren for doing this //UFN
  25. UFN
    2 pairs of amp boards and two dual supply boards. Possibly another pair of amp boards and a pair of the single supplies depending on price/availability. //UFN
