just tried to build this and I cannot confirm if it is verified.. I suspect I might have faulty/fake lm13700. I'll order some new ones soonish and report back.
OK, I took some time with the schematic today. There’s definitely errors in IC4. If you’re able to look at the schematic compare where the 3U capacitor should be going to. Also look at the 10k resistors that ought to be connecting with pins 8, 7, and five. If I come up with an easy way to move things around, I will share here!
Compare IC4 here with IC4 of the tagboard layout version. You will see what I mean about the 10k resistors and 3u cap. Using the schematic, along with the tagboard version as reference, should allow you to make the needed revisions here. I marked up a version, but I’m unable to share here
Is it verified??

Deleteit doesn't work (
ReplyDeleteThe schematic is available on pedalpcb, I believe. I have not gone through the whole circuit, but i would look for any voltages that don’t make sense.
ReplyDeleteI've assembled this circuit twice, but by a different author, and everything works perfectly. Unfortunately, it didn't work with this version.
