DEMODULATOR ALIGNMENT PROCEDURE
- (1) Voltage Controlled Oscillator (V.C.O.) Alignment
- (2) 30KHz Level Adjustment
- (3) Demodulated Voltage Alignment
- (4) Automatic Noise Reduction System (A.N.R.S.) Alignment
INSTRUMENT REQUIRED
- CR oscillator
- SCA signal generator
- Oscilloscope
- Vacuum tube voltmeter (V.T.V.M.)
- Attenuator
- Test record (4DE-503, RG-1256, RG-1257)
Preliminary
- 1. Connect instruments.
- 2. Set the receiver's selector switch to PHONO.
- 3. Set program mode switch to DISCRETE.
- 4. Connect lead wire between the junction of pin 15 on the printed circuit board (NADE-240a) and chassis ground. Then MUTING ON works.

LINE VOLTAGE AND FUSE
The model TS-500 operates on one of the four line voltages, 110V, 120V, 220V and 240V. Set the unit to the proper line voltage by following the procedure described below.
CHANGING LINE VOLTAGE SETTING AND FUSE
Turn the fuse cap located on the line voltage selector counter-clockwise.
Then remove the fuse plug from the unit. Put the fuse plug back so that the proper line voltage mark can be seen through the cut on the edge of the plug.
Whenever the position of the selector is changed, check the rating of the fuse. A 3.0A fuse is for 220V or 240V operation and a 5.0A fuse for 110V or 120V operation.
FUSE REPLACEMENT
When the fuse has blown, remove the fuse cap and replace the fuse with new one. See Fig. 1. The fuses are as follows.
| AC fuse | 3A-T(ST-2)UL(220/240V) |
|---|---|
| 5A-T(ST-2)UL(110/120V) | |
| Pilot lamp fuse | 3A-T(lead type)UL |
| Speaker fuse | 3A-T(SS-2)UL |
REPLACEMENT OF THE POWER IC.
- 1 Take off the Back Panel. (off 4 screws)
- 2 Take off the Heat Sink.
- 3 Replace the Power IC.
