Adjustment Procedure Align alternating with L 607 (1) at 531kHz for 1.1V 50mV and with C 627 (2) at 1602kHz for 8.0V 50mV. At 153kHz align with L 608 (5) for 1.3V 50mV. Check at 279kHz for 4.8 - 6.5V. Align alternating with L 603 (3) at 558kHz and with C 609 (4) at 1548kHz for AF maximum.

2. LW Oscillator

3. MW Band Pass

4. LW Band Pass

Align alternating with L 604 (7) at 162kHz and with C 611 (8) at 261kHz for AF maximum.

5. AM IF

Align with F 601 (9) for AF maximum.

6. FM Oscillator

Align with L 04 (A) for 2.8V 50mV.

7. FM Demodulator Preset

Align F 106 for mechanical center at which the voltage is > 1V.

8. FM Band Pass

Align L 03 (B) and L 01 (C) for a maximum.

9. FM-IF

Align F 101 (D) for a maximum.

10. FM Demodulator

Align F 106 for AF maximum.

11. Stereo Decoder

Set R 127 (F) to full clockwise position. Modulate the left channel an set R 204 (G) for maximum Crosstalk Attenuation at the right channel. Now modulate the right channel and look for the crosstalk attenuation at the left channel. If the difference is > 3dB, set R 204 for equal attenuation. Set R 127 (F) for a channel seperation of 12dB.

E = 45dBV = 178V.

2. Tape Drive

Adjustment 1. Azimuth

Preparation Connect an AF-Voltmeter to Speaker Output right channel. Play test cassette 448A (10kHz-part) in reverse direction.
Adjustment Procedure Adjust with screw A for maximum level. Control: Difference left-right channel: 3dB.

2. Tape Speed

Connect a Frequency Counter to Speaker Output right channel. Play Test Cassette 448A (3150Hz part).
Adjust with motorpoti for 3150Hz.
