DISASSEMBLY PROCEDURES (REFER TO PAGES 4 AND 10)
Note: When replacing parts, discharge by shorting between
terminals of the capacitor (C51 , C52) at the power
source with 8D 1O0W resistor as it may have
charge accumulated.
IIJ CABINET BOTTOM ASSEMBLY (101) REMOVAL
Remove 7 screws ~ and remove the Cabinet Bottom
Assembly (101).
IZJ MAIN P.C. BOARD (PCB-1) REMOVAL
1. Remove the Cabinet Bottom Assembly (101). (Refer
to step rn .
2. Remove 9 screws fY and remove the Main P C. Board
(PCB-l) with Cabinet Back (142), Line Input P
Board (PCB-2), Bridged-Mono Switch P C. Board
(PCB-3) and terminals (TEl and TE2).
3. Unsolder the lead wires from the Line Input P
Board (PCB-2) and Bridged- Mono Switch P.C. Board
(PCB-3) and remove the terminals (TEl and TE2)
by unsoldering.
4. Remove 2 screws ~ and remove the Cabinet Back
(142) with the Line Input P C. Board (PCB- 2),
Bridged-Mono Switch P C. Board (PCB-3) and ter-
minals (TEl and TE2).
PROTECTION CIRCUIT
If the temperature inside the CA260 rises above 80
the protection circuit comes into operation, decreasing
output. At this time the protect indicator blinks. If the
temperature comes back below 80 C by natural cooling,
output returns as it was.
If the temperature rises above 100 , the power supply
circuit is shut off. Not only does the output stop, but
also the protect indicator goes out. If this happens, it
is possible that the CA260 is broken. However, even in
this state, it cannot be always said that it is broken
because the unit may operate when the temperature
comes back below 80 C by natural cooling.
~ POWER SUPPLY P.C. BOARD (PCB-4) REMOVAL
1. Remove the Cabinet Bottom Assembly (101). (Refer
to step rn .
2. Unsolder the lead wires from the Power Transformer
(Tl ).
3. Remove 7 screws C!) and remove the Power Supply
C. Board (PCB-4) with the Cabinet Back (143),
Fuse with Holder (Fl), Insulator (186) and terminal
(TE3).
4. Remove the terminal (TE3) by unsoldering.
5. Remove screw C) and remove the Cabinet Back
(143) with Fuse with Holder (Fl), Insulator (186)
and terminal (TE3). At this time, disconnect the
connector from Fuse with Holder (F 1).
141 POWER TRANSFORMER (T1) REMOVAL
1. Remove the Power Supply P C. Board (PCB-4).
(Refer to step
~ .
2. Remove 4 screws () and remove the Power Trans-
former (T1).

ALIGNMENT PROCEDURES (REFER TO PAGES 9 AND 10 )
-Idling current adjustment
Conditions:
-Connect the DC voltmeter between TPl and TP2 and
between TP3 and TP4.
-Connect a 13.8V power supply to the 12V Battery
Power In terminal.
-After the power on, wait for 5 minutes before measur-
ing to be sure of the most stable operation.
Inspection:
-Confirm that the idling current is 50mA :t 20mA
(voltage: 33mV:t 13mV).
If the current measured does not fall within the range
specified, adjust it with the procedure below.
Adjustment
Note: When replacing or disconnecting a resistor, disconnect the power supply first.
Current Voltage Procedure
less than 29mA less than 19mV Add R481 and R482 between TP5 and TP6 and between TP7 and TP8.
71mA ~ 100mA 46mV ~ 66mV After cutting out R477 and R478, add R481 and R482 between TP5
and TP6 and between TP7 and TP8.
101mA ~ 200mA 67mV ~ 132mV After cutting out R479 and R480, add R481 and R482 between TP5
and TP6 and between TP7 and TP8.
201 mA ~ 250mA 133mV ~ 165mV Cut out R477 and R478.
more than 251 mA more than 166m V Cut out R479 and R480.
After the adjustment is complete, let the unit settle down for 10 minutes, than double-check that the idling current is set
properly.
