Neve 1290 gain pot issue

Hi all,
Rather than me sit there for hours trying To figure this out I thought I’d ask in here, as my time is limited at the moment.

On two channels of 1290 all gain positions work fine.
On the other two I have the same problem so it seems I made the same mistake twice!!
The gain positions work fine until the 8th position, so 8,9,10 and 11 positions are very low signal?
I’ve checked the potentiometers and they checkout with correct resistors.
So this leaves the pcbs with either a missing connection, missing component or a dry joint!
Just wanted to know where to look on the ez1290 schematic for positions 8,9,10 and 11 please?

Without looking at the schematic, I would say that many Neve preamp designs use the second "half" of the BA283 card for additional gain at higher settings.  I would start there.

Sorted it, cleaned pcbs and found a stray bit of solder Bridging an area on there, works great now!!!
