Official 33609 builder's tread. See 1st page for updates.

I don't think the DR 609 are the same pcb's as Igors. Therefore you are asking in the wrong thread. I believe there is a thread specifically for the DR609. Maybe you could ask there since there will be people who have built the project you are working on.

Yes, you´re right. The opamp boards layout is not the same, same circuit though
