Calrec FX1340 Mic pre conversion

[Otterhead]

Hi, New on here.
Have some Calrec FX1340 telephone distortion modules that have been converted to mic pres. I need to do some tweaks but don't have the schematics.
Where would be the best place to poke about here? I did a forum search for Calrec FX1340 and nothing came up..
Cheers!

Looks like those were in the M Series desks? Also looks like getting any schematics from Calrec isn't going to happen judging from people's previous attempts.

Yes I tried Calrec and they couldn't help. Any Calrec M Series desk owners out there?
