    Are there any excellent inexpensive Chinese DACs?

    As the GB is version specific, please report any building experience or issues here. The document is for your private use and not to be publicised, in order to avoid poor copies. Happy soldering, Patrick

    Gimmick or Legit? 🔥

    Could it be Patrick and Andy are not in disagreement: proper stuffing might achieve the same results, but the absorber array is a heck of lot cheaper to use (and is more consistent) in large series production of the drivers?

    a hybrid SIC jFET: UJ3C120150 - any experiences?

    Those are Nelson Pass specials. Not the "normal" Semisouth's that normal people are talking about. :giggle: Patrick

    Adaptor PCB 2SK2145GR as 2SK170BL Substitute

    Thanks Patrick, maybe I've missed something, but in order to parallel the two Sot-23 parts, their layout should be reversed on opposite sides? All the double-sided boards appear to have the same orientation on both sides.

    An F5 with laterals

    Oh, also try higher bias for Q26,27 and see how distortion changes. Patrick

    The Kaneda No.168 Preamp

    The second stage bias is not 0.4mA. All the information one needs to build the real thing is in the BoM, and of course the Gerber. I know what I have built. And I know what DC currents I have, in real. Cheers, Patrick

    Preamplifier Dispre 2 - JFET

    BTW, if you are still using BD139/140, may I suggest you give TTA/TTB004 a try ? My standard go-to parts for TO126 BJTs these days. Patrick

    QUAD II mono amp/control unit/tuner (old model-1960)

    ...They have an optimum 'load', so the pencil marks show an alternate 'strapping' on the binding posts on the OPT to reflect the correct load. Patrick Turner (RIP), a fellow antipodean, goes into a lot of detail about the reflected loads and the response curves on his site, Patrick Turner...
