    Just basic JJ El34's. From what I understand, different tubes should have limited sonic inpact in this curcuit, but I got the GB BH boards for a later build and there I think changes may be more audible. Apart from looking for exotic, I also intend to try the JJ EL-34L which the guitar crowd claims had more bottom end than the regular JJ EL-34. Fun times ahead

    Well, vacation is over and my GG lives. Turned out to be a partially dead lsk389 on one channel and a cold solder joint on the other, combined with too high tail resistor values on both. Obviously not my finest hour stuffing those boards . Anyway, the amp sounds really really good, so many thanks to KG and all other contributors for this great circuit! Now to find some exotic and good looking EL-34's to top it off...

    If that's the board from page 2 of this thread, I don't think it has a servo on board...

    Very good guide. I'm away vacationing for a few days, so this will be next sunday's mental exercise. Whatever the error is it's symmetrical, cause both amp boards are acting up identically. I'll post back once I've investigated a bit more...

    Looks excellent! Trying to sort mine out as well, was suspecting the lsk389 are dead because while voltages are fine with inputs shorted they go crazy when fed a signal, but a cold solder joint on the nfb might explain that as well. Where did you find the rings for the top lid? They look great!

    Package arrived here also. Many thanks!

    If you have (or can get hold of) a british IP-address when signing up: http://www.qobuz.com/gb-en/plans/music-streaming-subscription Great for jazz and classical.

    Second that. Some nice write-ups based on actual testing of different cable types, including USB: http://archimago.blogspot.se/2015/06/musings-audio-cables-summary-non.html Summed up; if your DAC is asynchronous (i.e. the computer is not doing the clocking), every cable which meets USB2.0 requirements will perform identically.

    Paid. Many thanks!!

    Yeah, apparently the car was not meant for any employee to just take for joy driving . I'll have to make some friends in higher places first. Next GB though...

    Interesting. Always was a Tuborg fan; guess the exotic stuff from other countries taste better :). Also, In Sweden, beer commercials were not allowed when I was that youngster age, so the only promotion available was from Tuborg. - Du Perikles - ka' Du sige mig - hvornår smager en Tuborg bedst? - Hvergang! Guess that had an influence...

    Good to know that I will have full moral support and backup when trying to explain why that nice demo car had to have some uptime

    Indeed Coincidentally, I walked by a 450+ BHP Volvo S60 Polestar this morning when going to a meeting at work; I briefly considered "borrowing" it and just make a run for the border with gwrskien's boards.

    All european destined boards have now been shipped onward from the swedish hub. PMs with shipping costs will follow tonight.

    No worries, take the time you need!

    Nothing to add, looked alright in the gerber viewer...

    No need to wait I think, the board is done: http://gilmore.chem.northwestern.edu/boards/baseboardbal4a.zip A place to insert attenuator of choice and then space for two smd buffers. That was the wish list, right?

    From Kevins comments, the reworked one would be a fair bit bigger and this is already quite big, so I'd prefer the smaller, current, version.

    Stuff arrived

    paid, thanks!

    As am I! A really great piece of work!

    As far as I can tell; yes. Not an expert on how to set up the MAX4820 though.
  23. MLA
    Smaller board fits my needs better, but I would of course be fine with a bigger, more feature rich, version.
  24. MLA
    So, I would start with reflowing all solder joints and also double check that your R8 actually is 860R. Pic of the board would help trouble shooting.

    I'm in too.
