I seek infos on the diagrams used by Musical fidelity for their Nu-Vista series
Click to expand...

Unless you write Musical Fidelity and tell them you own one and you need a schematic, it is difficult to get that information. Manufacturers are generally loathe to give out information on their circuitry, not necessarily to protect their design, but to hide its simplicity. I am speaking of tube amps where there is nothing really new.

Musical Fidelity have a policy of not giving out diagrams even if you can prove you own the equipment in question. I once had a Digilog (DAC), so I traced out the diagram and found it to be a hotch-potch of semiconductor manufacturer's application notes - no wonder they didn't want anyone seeing what they'd done! You can do the same, open it up, and use the web to find data sheets for each IC, valve, and transistor, then trace out the diagram.

Students!

I take your point - after all, the semiconductor manufacturer knows best how to use their device. On the other hand, their application notes (of necessity) are general purpose, and not optimised for a particular application. I would expect (and demand) rather greater optimisation and originality from a professional manufacturer than I would expect from a final year project student.
