8.1 General Information
The schematics referenced and provided are repre-
sentative only. There may be slight variations between
amplifier to amplifier. These schematics are intended
to be used for troubleshooting purposes only.
Note on circuit board designations: Crown circuit boards
are referenced with a PWA and/or PWB part number.
PWA stands for Printed Wire Assembly. This is the com-
pleted circuit board with all components assembled.
PWB stands for Printed Wire Board. This is the circuit
board only, without components.
