Very clear copy. No pages missing. Big bonus is that it includes supplement. Price is affordable compared to what others ask for.
Found the quality of the copy excellent and a very quick service. I would certainly recommend the service.
Good quality, clear diagrams. Exactly what I needed.
Good product. All the information is invcluded, but due to the complexity of the amplifier, it still is difficult to get it to operation again.
Very professional seller; very fast, accurate and rielable service.
