I searched the Internet exhaustively for this manual and Owner-Manuals was the least expensive...but provided an excellent reproduction within 4 hours. Very satisified.
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.
