  1. It looks like that the download link do not work, is it only me?

  2. Yep download link is definitely broken. I suspect the file is still being uploaded?

  3. I like the way you go about trouble shooting, which is something I’m still learning , I have to make notes at each step, which I find helpful at this early stage of development.
    Really enjoying it Dave, learning the art of fault finding.

  4. Could be a boat anchor, there are so many failure points yet it could be one sneaky component failure this could could put Dave to the test. Hope the gods of electrical failure favors Dave

  5. Hmm, while we know the failed diode is now allowing -19v to the board what we don’t know is what voltage the failed PSU presented to that diode & regulator.
    If, for instance, the failed PSU was sending -40v to the regulator and diode and the diode sorted, then -40v (more or less) will hit all the -15 components. Thet would easily kill some of the op amps, etc…

    Not to mention what may have happened to the components expecting the -5v or the -12v on the other board.

  6. Really interesting, would be good to see you persevere with this!
    Very good troubleshooting practices!

  7. You’re so awesome! I don’t believe I’ve read a single thing like this before. So nice to find another person with original thoughts on this subject. Seriously.. thank you for starting this up. This website is one thing that is needed on the internet, someone with a little originality!
