I fear that there is not much to find anymore. Have you already tried reverse-engineering a module?
The documentation of the MD16, rather standardised, transistorised mixing console from 1968, is fully available on the web, but that's probably not of much use to you.
Over here, for exemple: https://groupdiy.com/threads/1968-philips-md-console-troubleshooting.57482/
https://ekadek.com/2019/06/05/ekadek-ferralgraffa-twin-preamp/
Here you can find the reverse-engineered schematic of a Dutch broadcast preamp, wherein Philips may or may not have been involved.
Could you post more photographs please, maybe in a new thread?

Maybe send him a PM (it's called "Start Conversation" in GDIY lingo)
Posting the first photos of Philips console restoration.
Looking for schemes and diagrams.
Already get in touch with Philips Museum in Netherland.
All help and info will be welcome!!!

Also interesting that it seems to be hybrid.
Looks like the EQ section is solid state (maybe comparable to the MD16 EQ?).
What module is in photo 19? Germanium pre? Is that the same as those in the top row like on picture 19? They seem to have bass/treble controls (H + or -, so 'hoog' or high, I can't read the other letter) - seems like that could be echo sends or returns, to equalize that a bit (chamber echo), especially since they are more like trim pots.
I'm a bit puzzled by the row of valves in 13, because they are not on any kind of module or something, like the rest.
I'm just saying whatever comes to mind. I'm really interested to see how it really is, maybe with some schematics.

So the modules in photo 19 (and I suppose photo 8, the row above the EL3710s), are EL3660s? Odd that the pots don't seem to correspond.
