It still doesn't indicate which part is for which version, though. For R27,28, it lists 10k and 8.5k. The schematic lists 6k or 7.5k. And I've found a modification notes that specifies replacing the 7.5k with 6k (which is what I actually have on my unit). None of this explains how to interpret line R27,28 :/
The totals column suggests that for each of the resistors, there are two values used at the same time, not either/or.
Could it be that they are two in parallel or in series on the PCB?
Like R31, R32, each consist of 62k + 33k, in parallel or in series.
The values are also too different to be for different versions.

I agree with Jan that both values are used simultaneously, but I think the quantity column is indicating what is needed for 2 channels.
That seems unlikely, I can't imagine that, for instance, one channel needs 62k and the other channel needs 33k for the same resistor.
Does someone have an actual PCB? That would clarify it quickly.

No, not what I meant at all. If you notice, the quantity column is only filled for the top line of the double resistor entries, so you need 4 resistors in total for 2 channels for those.
Yes, I know what you mean, but I interprete it differently.
Really curious what it really is.

I looked at quite a few schematics and part lists from AR and they all have the same weird notations.
I think they are ment to cover the different revisions but this is never explained anywhere as far as I know.

That's completely broken list, most of the quantities are wrong, I suspect it was regenerated and merged with another version at some point and got into a complete state that's been left to confuse and confound. My best guess is someone foolishly decided to renumber all the parts, or merged designs with clashing part numbers...
It’s definitely not doubled up resistors, I can verify that by looking at the board.
Guess I’ll just have to read the values off the parts…
