Note for Replacement of the Transistors
The transistors Q111, 112, 114, 115, 117, 118, 211, 212, 214, 215,
217 and 218 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.
217 and 218 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.
