• Note for Replacement of the Transistors
The transistors Q110, 111, 210 and 211 have two different ranks: P
rank and Y rank.
The rank of these transistors need to be selected properly according
to each channel. When replacing any one of these transistors, check
its rank and replace with the appropriate transistor of the same rank.
