1. This part is not normally available from Customer Service. Approval from the Field Service
Manager is required before ordering.
2. The individual parts located on the PCBs are listed in the Electrical Parts Lists.
3. This part is critical for safety purposes. Failure to use a substitute replacement with
the same safety characteristics as the recommended replacement part might create shock, fire
and or other hazards.
4. The PCB assembly 199831-101C has a change to the AM circuit and uses a new AM an-
tenna part number 199824-002. The PCB assembly 250737-101C has a change to the FM
circuit in addition to the AM changes on the 199831-101C PCB. When replacing an older PCB
assembly with either one of the PCBs (199831-101C, 250737-101C) the new AM antenna part
number 199824-002 must be used with the new PCB assemblies.
5. These parts are not used on the 250737-101C PCB assembly.
6. This part is used on the 178335 PCB only. The 178335 PCB is the original PCB used on the
CD-20. Most of the parts listed are common to all of the PCB variants.
7. This part is used on the European variant.
8. This part is used on the Japan variant.
9. This part is used on the Dual voltage variant.
10. The PCB part numbers 178349-101C and 199831-101C are no longer available. They
have been replaced by PCB part number 250737-101C. When ordering a new PCB assembly,
use part number 250737-101C and order the new AM antenna, part number 199842-002. Due
to design changes in the Am section of the PCB 250737-101C it is important to use the new
AM antenna, part number 199824-002, for proper impedance matching.
