field-replaceable. We have endeavored to include all field-replaceable parts in this list.
However, some non-field-replaceable parts have been omitted.
See the following assembly drawings for locations of components.
Obtaining Spare Parts
Special or subtle characteristics of certain components are exploited to produce an ele-
gant design at a reasonable cost. It is therefore unwise to make substitutions for listed
parts. Consult the factory if the listing of a part includes the note “selected” or “realign-
ment required.”
Orban normally maintains an inventory of tested, exact replacement parts that can be
supplied quickly at nominal cost. Standardized spare parts kits are also available. When
ordering parts from the factory, please have available the following information about the
parts you want:
Orban part number
Reference designator (e.g., C3, R78, IC14)
Brief description of part
Model, serial, and “M” (if any) number of unit ⎯ see rear-panel label
To facilitate future maintenance, parts for this unit have been chosen from the catalogs of
well-known manufacturers whenever possible. Most of these manufacturers have exten-
sive worldwide distribution and may be contacted through their web sites.
