<div dir="ltr"><div dir="ltr">I remember when this happened with Cool Audio 2164s which caught a lot of people off guard. Here's a thread from a few years ago about the 3205s, presumably the same seller: <a href="https://www.diystompboxes.com/smfforum/index.php?topic=120965.0">https://www.diystompboxes.com/smfforum/index.php?topic=120965.0</a> </div><div dir="ltr"><br></div><div>Nathan</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Aug 16, 2021 at 11:58 AM Didrik Madheden via Synth-diy <<a href="mailto:synth-diy@synth-diy.org">synth-diy@synth-diy.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">The "fake" chips are often real, but defective, chips salvaged from<br>
old equipment that are "refurbished" with a new coat of varnish and<br>
some new text painted on. It's not impossible that one (or all) of<br>
them had their new coat of paint on backwards. Try rubbing the top<br>
with Q tip soaked in acetone to see if you can find out what the chip<br>
really is, and with orientation it's supposed to be in.<br>
