i have a 1285 module, but no schematics, but you should be able to trace the wires from the transformers, transformer pinout, you can find on the webs.
I have the schematics. I some how came across several Neve BA 214 amplifiers in my collection of stuff. Planning on making them in to mic pre amps. The prototype I did sounded great. Pongi can you post a picture of the 1285 module. pucho812 would be happy to share the schematic.
kindest of regards
