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

Trying to trace my own 33609 PCBs based on original schematics.
Have a couple of questions.

In original layout, some signals are "screened" with ground tracks coming around.
I only found one good photo of the upper side of Comp/Limit PCB and judging from here
P2-6 (gain makeup) and P2-4 (compress switch HIGH) signals are surrounded by ground tracks.

Also, according to schematics, signal outputs P3-9, P3-10 must be screened, but seems like they are on the bottom side, so I can't examine these.
Also P2-9 (compress ratio), P2-3, P2-4 (compress switch LO, HI), P1-5 (comp threshold) must be screened, but as I see on the front side,
P2-3 (compress switch LO) is traveling through the board without any ground traces (I've marked this track with UP arrow and question sign).
My whole question is, is it necessary needed ? Does it save the signals from interference that much ? Shall it create unwanted ground loops ?
It would be cool if somebody have a bottom layer photo or layout to watch.
Thank you !
