jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
Instrukcja jest OK. Schematy czytelne, opisane niektóre procedury.

XR-CA350X SECTION 3 MECHANICAL ADJUSTMENTS
1. Clean the following parts with a denatured-alcohol-moistened swab: playback head pinch roller rubber belt capstan idler 2. Demagnetize the playback head with a head demagnetizer. 3. Do not use a magnetized screwdriver for the adjustments. 4. The adjustments should be performed with the power supply voltage (14.4 V) unless otherwise noted. Note: With this set, it is not necessary to apply suitable locking compound to the parts after the azimuth adjustment. � TORQUE MEASUREMENT
