Help with DBX 160vu calibration?

[earthsled]

Hi all -

Has anyone done this before? I have a copy of the procedure (attached), but I haven't been able to find a PCB layout with component designations. So, when the procedure reads, "Turn trim pots R27 and R34..." I have no idea which trim pots they are!

To make matters more confusing, one unit I'm working on has 7 trim pots inside, and the other has 9 (plus some extra components near the VCA module).  ???

Any 160vu gurus out there?

Thanks!

draw the layout then label the parts by looking at the schematic.

or hope that someone who has done this before has a copy they can post.

even then it needs to be checked.

Earthsled, PM me your email address and I'll send you what I have for the 160VU.
Meanwhile, I've also sent it to Ethan for inclusion in the Tech Docs section.  (3.2MB)

Hi, I'm re-calibrating a 160vu and something is not so clear to me on the calibration instructions, the RMS module in this unit is 208 and section 2A relating to "COMP PIN".
According to the 208 pinout there is no "COMP PIN" on the 208.
So what is the right pin according to this pinout?

It seems like pin 3 is the "COMP PIN"
