Javier I am in the same position except that I just made a deal for a pair of them. Were you ever able to lay hands upon the right schematic?
EVERYONE ELSE: Hi! This is my first post! this place is great! Can you help us out please? We need Trident schematics! I am planning to rack mine with I/O and stereo faders in a box (like the S80 producer-thingy), long with a US mains-compatible power supply.
Any suggestions on the PSU, if nothing else? A friend — not a tech — suggested just buying a power supply in the correct range from Acopian or the like … anyone gone this route racking up other gear, or even Trident channels?
FIVE MINUTES LATER:
Hey Javier I found another thread here about Trident PSUs. Gearslutz user obostic has posted pics of the power supply schematic from an 80B manual (with corrections).
