Parts List

Control Board
Many parts used in the 6300 are surface-mount devices ("SMT") and are not in-
tended for field replacement because specialized equipment and skills are necessary
to remove and replace them. The list below includes substantially all of the parts
used in the 6300 (including surface-mount devices), and inclusion of a part in this list
does not imply that the part is field-replaceable.
The input amplifiers, output amplifiers, and tee-filters (used for EMI suppression) are
socketed and easily replaceable. These are the components most vulnerable to dam-
age caused by severe EM surges, such as those caused by lightning strikes at a
broadcast transmitter site.
See the parts locator drawings for locations of components.
Special or subtle characteristics of certain components are exploited to produce an
elegant 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
"realignment 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 informa-
tion about the parts you want:
