service manuals ?

I have just become owner of a revox a 77 tape machine. As the prices for revision of this machine are somewhat outrageous, I 've decided to do what I can myself. A service manual, of course, would be a great help. Has anybody an idea where I could get one of those? Or has anybody experience in this kind of venture which he/she could share? Keep on wheeling!

My name is Dario and I live in Slovenia near the Austrian border. I have just get an old OAKLEY ''Image Six'' tube pre-amp as a gift from a friend. The unit need to be repaired but I am not the first one that try to do it. Someone put a few parts out but not back again. So the only possibility to repair this thing is to get a service manual - but where !? Has anybody an idea where I could get one? Thanks for any help and greetings from Slovenia !
