Parts Included in All K3 Kits
These parts are in a box with a label identifying the contents as a K3 kit and whether it is a K3/10 (10 watt) or
K3/100 (includes the optional 100 watt KPA100 amplifier).
Your kit should include all of the following parts regardless of the options you chose. Note that there are two
additional boxes. One box contains the large K3 BSF (main RF board) (see page A-15) and the other box
contains the chassis set (see page A-16).
Printed Circuit Boards
Each board is packaged in its own ESD-safe bag identified by the part numbers shown below. The photographs
are provided to help you identify each board. You may find that some of the components or component
locations on the boards you receive are slightly different from those shown.
CAUTION!
DO NOT DISTURB ANY ADJUSTMENTS ON THE BOARDS
Each board was tested and aligned for optimum performance at the factory. Any change to these
adjustments will degrade the performance of your K3 or prevent its operation altogether. All user
calibrations and adjustments are done in firmware using the front panel menus. These are
described at the appropriate points in the assembly procedures and in the Owner’s Manual.
