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!
