Ah no, the service manual is something which must be acquired separately, definitely quite different from the owners manual. This is also often the case with audio companies, though many do not offer anything. Companies like Denon, Rotel, and many others do provide very useful and complete service manuals upon request, which provide everything from schematics, a BOM, board guide, and exploded assembly guide.
My sensei's favorite insult was always that one's mother wears combat boots.
