Replacement of Power Transistor, Speaker
Protective Relay
It is easy to replace the power transistor and speaker
protective relay of this unit according to the following
procedure.
a. Remove the top cover. (Refer to “1. Top Cover
Removal” on p.18.)
b. Remove 1 screw (B) and 2 screws (C). (Fig. 6)
c. Raise the MAIN P.C.B. (Fig. 7)
d. In this state, the power transistor and speaker
protective relay can be replaced. To check the
operation in this state, it is necessary to connect the
grounding cable.
