1- 10. Differences in Equipment Improvements in the Phase Rotation Circuit
(oscillator function) were incorporated starting with serial Numbers
8220-841-24 and subsequent. Most of the changes were made in the Printed
Circuit Board Assemblies A21 and A22. Some minor change was made in the
Main Wiring Harness. All differences and equipments affected are identified
in this manual.
