Default RME Octamic II input circuit anyone

Hello Badcappers.
I just finished wasting time contacting RME for any useful information on the Octamic II preamp. We have been repairing these for some years (with no help from RME). These are expensive devices with cheap unreliable components inside. Caveat emptor.
Anyway, we are managing to repair them all the same, usually by replacing the dodgy switchmode power supply with something reliable, but recently I thought it would be nice to actually repair one of these devices, rather than replacing boards in them. A likely candidate came along with just one channel out of 8 showing no output. Surprisingly, this one actually had a working power supply, which was nice.
Measuring voltages I could see 9VDC on the negative side of most of the caps in the faulty channel. Obviously not meant to be there, especially when compared with the other channels.
Anyway RME wouldn't even drop a hint as to how their input is wired and the attached guess is just a guess. So cut a long story short, anyone ever mapped out the input to ANY similar RME devices as I'd bet they all are the same?
