As a rule, replace ICs with only ICs of the same rank within each channel (right or left).

6、 2. If an IC of the same rank is not available, the IC of one rank higher or lower (see table 1 below) can be used instead. However. after re- placement, the ICs on the recording side and the playback side must not differ by more than one rank. 3. The colors in table 1 refer to the color marking on

7、the top surface of the IC package (see fig.l). Ranking color Example: Acceptable replacement: Rank does not differ within each channel. Unacceptable replacement: o In this example, the rank of yellow and violet are more than one rank. H I G H t LOW I LchRch Recording Side PA3012-01-RPA3012-0t -Y Pla
