Front Panel Board Parts List<br />

The following table lists the electronic items incorporated in the Front Panel<br />

Board and should contain any part necessary for normal electronic repair. Unless<br />

otherwise specified, call outs of manufacturers and manufacturers' part numbers<br />

are to be considered typical examples only and not restrictions against using<br />

equivalent parts with the same operating characteristics. When ordering parts<br />

from Eberline, specify model number, serial number, reference designation, value<br />

and Eberline part number, or a word description if the part has no reference<br />

designation. Eberline will automatically substitute equivalent parts when the one<br />

called out by the manufacturers' part number is not available.<br />
