This document is just what I was looking for, it´s very useful, it contains adjustment procedures for the final stage of the power amp and also
has a complete wiring diagram and description of the main semiconductors used in the design.
Dear Sirs,
Thank you for the fast support, the manual does provide all necessary information to repair the radio. All schematics are in a good quality for reading.
The manual fits 100% to my requirements as a technican.
Kind regards Thomas

Procedure : 1. Connect oscilloscope to test point TP(TE) on BD board. 2. Turned Power switch on. 3. Put disc (YEDS-18) in to play the number five track. 4. Press the �P (Pause)� button. (Becomes the 1 track jump mode) 5. Check the level B of the oscilloscope�s waveform and the A (DC voltage) of the center of the Traverse waveform. Confirm the following : A/B x 100 = less than ±22%
