Error in new Noise+S&H PCB image |
 |
|
Hi,
I've just completed a Noise+S&H, etched from the latest (Nov 2016) PCB image available on yusynth.net. I plugged it in and everything worked fine except for the internal clock, so I started troubleshooting. Naturally I looked for something I had done wrong, so I went over every component in the oscillator circuit several times and found no fault.
Finally I noticed a discrepancy in the PCB; the trace that goes to pin 3 of the TL071 has been mistakenly drawn to pin 2 in the PCB image! I broke the trace at pin 2 and put a bodge between the trace and pin 3; it now works flawlessly!
I'm guessing I'm the first to build the combo board since the last update, so hopefully this will help someone who might have used the new image before a fix goes live on the website.
And to Yves, if you read this, thank you again! I'm having the time of my life with this build.

I was in the middle of building one and saw this, you probably saved my a half hour or so. Thanks! |
