The delivery of this manual was very fast, less than 8 hours. The manual is very clear and concise, and helped a great deal in the repair and final setup of the Hitachi HMA-G2 Amplifier.

Great service. The manual was exactly what I was looking for: schematic + layout. I managed to fix the player. Highly recommended!
1. Focus Offset Adjustment a) Connect an oscilloscope between test points (FEl) and (VREF). b) Turn on the main power to the CD player (CD STOP). c) Adjust SFR302 so that the Offset level becomes OmV with reference to VREF. 2. Focus Bias Adjustment a) Connect an oscilloscope to test points (RFO) and (VREF). b) Insert test disc TCD�782 (YEDS-18) and PLAY BACK track No.2. c) Adjust SFl1301 so that the level of RF wave to be Maximum and clear.
3. Tracking Balance Adjustment a) Connect an oscilloscope to test points (TSO)and (VREF). b) PLAY BACK test disc TCD-782 (YEDS-18). c) With F> or<< button pressed, adjust SFR304 so that the wave form on the oscilloscope is vertically symmetrical.
