Wanting to repair a neighbours tape recorder I needed the necessary information, it makes it easier. Although the service manual is described as "Language : English" To my dismay I found that it is entirely written in German, a language I do not understand. At least I now have the schematics which will help of sorts. I may not use this service again due to the laguage difficulty after all when it states English you do not expect it to be entirely in another language.
very poolite and healpful secure transaction thanks allot

SECTION 3 ELECTRICAL ADJUSTMENTS
The set should be connected to a master unit for electrical adjustments (See page 2). Local OSC Adjustment Setting:
ANTENNA jack
oscilloscope main board TP LO
Frame Sync Adjustment Setting: ANT +B switch : ON
oscilloscope ANTENNA main board TP IF2 CH-1 set CH-2
Procedure: 1. Adjust T102 so as to maximize the peak of waveform at 35.84 MHz. Adjustment Location: See page 6. IF2 Output Gain Adjustment Setting:
digital voltmeter main board TP LEL
main board TP FSYNC
Procedure: 1. Receive the DAB signal. 2. Adjust RV104 so that the rising edge of waveform of TP FSYNC is positioned A. (1) In case of Band ��� (from channel 5A to 13F)
TP IF2
TP FSYNC
Procedure: 1. Adjust RV101 so that the reading on digital voltmeter is 2.25 V. Adjustment Location: See page 6. AGC Adjustment Setting: ANT +B switch : OFF

TP FSYNC
Procedure: 1. Set the carrier frequency of RF SSG to 225.648 MHz. 2. Receive the channel 12B (225.648 MHz). 3. Adjust RV102 so that the reading on digital voltmeter is 3.1 ± 0.5 V. 4. Set the carrier frequency of RF SSG to 1471.792 MHz. 5. Receive the channel L12 (1471.792 MHz). 6. Adjust RV103 so that the reading on digital voltmeter is 3.2 ± 0.5 V. Adjustment Location: See page 6.
