@ The power supply for this unit varies depending upon the areas. Also, the parts used for power supply are different.
So, refer to the circuit diagram and the replacement parts list.
* [XA, PC] areas is provided with voltage selector and AC outlets.
* 240V (50/60Hz) for Australia and United Kingdom.
* 220V (50/60Hz) for Continental Europe.
* 110V/120V/220V/240V (50/60Hz) for other [XA, PC] areas.
* Phono input capacitance is about 150pF.
M@ BEFORE REPAIR AND ADJUSTMENT
1. Turn off the power supply and short-circuit of power supply capacitors (C406, C407, 4700uF) at resistance (about
10Q, 5W) in order to discharge the charged voltage. Do not short between C406/C407 by screwdriver. It may
damage the component.
2. Before turning on the power supply after completion of repair, slowly apply the primary voltage by using a power
supply voltage controller to make sure that the consumed current is free of abnormality. The consumed current at
60Hz/50Hz in no signal mode is shown below with respect to supply voltage 110V/120V/220V/240V.
