NOTE FOR REPLACEMENT OF THE
TRANSISTORS:
TRANSISTORS:
The transistors Q110, 111, 210, 211, 310, 311, 410 and 411 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.
