Notes: 1. These assemblies must be clean and free from flux and all contaminants. Use of no clean flux is not acceptable.

2. These assemblies must comply with workmanship standards IPC-A-610 Class 2.

3. Ref designators marked with an asterisk ('**') cannot be substituted. All other components can be substituted with equivalent MFG's components.

4. If banana jacks (J1 - J2), (J8 - J9), (J11 - J12) and (J18 - J19) are supplied with solder lugs, dispose of lugs prior to installation on PCB. Solder lugs are NOT to be

installed on assembly.
