2. Precautions in Servicing
Notes:
• Both left and right channels employ the same class-B power supply circuit board (TPS-79). Identifications of the circuit board in the diagram are provided by prefix "L" for the left channel and "R" for the right channel, as shown in the example below.
Example: D501 for the left channel: L-D501
D501 for the right channel: R-D501
- Check ventilation carefully when a great deal of heat is generated. If the amplifier is installed on a dead-end rack, heat will accumulate and result in a reduction in the service life of the parts. Maintain a clearance of at least 5 cm on the top to assure sufficient air flow.
- Do not reverse the L and R SUBSONIC and DIRECT terminals since neither channel will function properly if the connections are incorrect. Be sure the L and R leads are properly connected to the correct input terminals.
- Do not mount the amplifier with the rear panel removed. The power cord may bend and become disconnected where it exits from the bottom of the amplifier.

3. Removal of Covers and Panels
Procedure
1. Side Panel
Remove four screws 1 on each side. Remarks:
- First remove the side panels to permit the parts to be removed.
- Be sure to follow the order of steps given here.
2. P.C. Board Cover
Remove the two screws(2), then slide back and lift up. Remark:
The front panel can not be dismounted until the circuit board cover is removed.
3. Front Panel
Remove screw(3) from above and two screws(4) from below, then pull the front panel out to the front. Remark:
The driver circuit board and power transistors can now be removed.
4. Bottom Cover

6. Adjustment Procedures
6-(1) Center Voltage (See Fig. 12)
- 1. Adjust R631 (or R632) to the midpoint before turning power on.
- Connect a voltmeter providing accurate voltages readings below 10 mV between test point C and the chassis of TAD-182 and 181 respectively, with the plus lead to point C and minus lead to the chassis. Then turn power on.
- 3. Turn R631 (or R632) little by little until the voltmeter reads 0 V.
Note: Speaker terminals may be used in place of test point C.
6-(2) Idling Current (See Fig. 13)
- 1. Turn the R645 (or 646) fully in the opposite direction to the arrow.
- Five to six minutes after turning power on, connect the voltmeter minus leads to test point C (or the speaker plus terminal) and the plus lead to test point E (of both TAD-182 and 181) then slowly turn the resistor in the direction of the arrow until the voltmeter reads 10 mV.
- 3. Check that the voltage between test point C (or the speaker plus terminal) and test point D is approximately 10 mV. Reverse the voltmeter polarity and check that the voltage between test point C (or the speaker plus terminal) and test point A is nearly equal to that between test point C and test point B.
- 4. After adjusting TAD-182 and 181, recheck the channel first adjusted. If it is out of adjustment, repeat the adjustment. (Adjustment repeated two or three times alternately for L and R is sufficient.)
- 5. The idle current has now been adjusted to 20 mA (13–32 mA).
