Andy,
I'm just about to take a flight to the UK, (booked it 10 minutes ago!) -I'll try to photocopy a set for you. (there's ten volumes to the 9K set... a full shelf's worth!!! -I can only manage a fraction before I go into excess baggage!) and I'll get my mum to mail them on to you.
Neve also used only +16V, -16V and -15V for the recall. Fets were switched from -16VL (Logic) and so they also may possibly have had the punch-through, though nobody ever complained...
I noticed that Neve always fed their gates through 1Meg gate feed resistance, SSL used 10Meg typically... -I often wondered whether there was a reason or effect for different gate feed resistances... but I'm a tech, not a researcher! :wink:

The 9K used a VCA and peak/RMS detection, both were SSMxxxx ICs from memory, though I can't remember more without digging into the shelf of Oxford's finest publications!what the 9k dynamics section looked like. Although it was my design I don't remember it at all! Was it like the 4k but using an MDAC instead of a VCA?
