Sansui AU-9900 bias help

So I found something interesting today when tryin to adjust the bias on my 9900, and might explain why the OP wasn't getting any movement when adjusting the trim pots... The manual page that is posted on the original post, and the one i was referencing, has the pots mixed up from what is actually in the amp!

I have VR01 as the far outside pot, but the manual shows it is one of the two middle ones... Seems like this could be causing the original problem!?

I am currently having a hard time reading the PCB to confirm the labeling on the other pots, but VR01 is definitely on the outside, at least on my amp!
 
It looks like VR01 and VR03 are backwards on the manual!? As well as VR04 and VR02

Can anyone confirm this? I am a noob and would like this to be double checked by someone else

EDIT: I have 100% confirmed this... at least on my amp. You need to swap VR01 and VR03... and also swap VR04 and VR02 as printed on the service manual page from the OP

The lasts two posts are correct, according to my AU-9900 also. Plus I would like to highlight a couple of other problems with the manual on this page. Here is the summary:

1) If we take VR01 (L) and VR02 (R) from the schematic and parts list, which is for DC adjustment, their position in Fig. 3-1 should be swapped with VR03 (L) and VR04 (R). I.e. from top to bottom:

VR01 (DC adjust L)
VR03 (bias adjust L)

VR02 (DC adjust R)
VR04 (bias adjust R)

So make sure you are sticking your screwdriver in the DC adjust pots before you go turning wildly trying to set DC.... if nothing is happening to your DC you might be in the wrong pot and about to cause a problem for your machine, or if nothing happens see (3) below

2) In the notes for DC adjustment the manual says "Set bias current to minimum VR03 and VR04 clockwise". The correct direction for reducing bias current is turning VR03 and VR04 counter clockwise

3) The manual shows in Fig. 3-2 putting probes into speaker SYSTEM-B to measure DC. This is fine, but the novice might not realize they should set the front panel speaker switch to B, and lets face it, most people have A as default, so this could be another reasons there are so many threads saying that adjust the pots does nothing. Use either A or B, and just make sure you connect the speaker outlets by setting front panel switch to appropriate position. Obvious, but you know how these things are :)
