available for me the service manual is in order!
thanks
 ;
This is exactly the thing you need to service this box. The manual is complete and the quality of the scan is good. I recommend this!
;
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!

At $5,00 certainly good bang for your buck. Includes electric schematics as well as exploded parts view + parts list for reordering. Unfortunately no details on the PCB contents or working, but then again, this is not overly complex. Best bonus: this manual does contain the heavily searched for LED error codes as well as descriptions for test operation. Haven't gotten around to fixing the machine yet, one thing the manual won't do for you is getting it out of the kitchen assembly :-(

Description
For the connection of the pickup photodiode. Addition to the FIN1 pin creates an RF signal and subtraction from it create an EF signal.
O O
For the connection of the pickup photodiode. For the connection of the pickup photodiode. Subtraction from the F pin creates a TE signal.
O I O
For the connection of the pickup photodiode. Inputs the DC components in the TE signal. For the connection of a resistor which sets the gain of the TE signal between this pin and the TE pin.

TE signal output. TES (track error sense) comparator input.The TE signal is passed through a BPF. Shock detection input. Sets the time constant for the tracking gain. TA amp output. Composes the tracking phase compensation constant between the TD and VR pins. Sets the tracking phase compensation. Sets the amplitude of the tracking jump signal (kick pulses). Tracking control signal output. Focusing control signal output. Composes the focusing phase compensation constant between the FD and FA pins. Composes the focusing phase compensation constant between the FD- and FA- pins. Composes the focusing phase compensation constant between the FA and FE pins. FE signal output. For the connection of a resistor whichs sets the gain of the FE signal between this pin and the TE pin.

Ground of analog signals. Single-ended output of the signals input to the CV+ and CV- pins. Spindle amp input. For the connection of a resistor which sets the gain in the spindle 12cm mode. For the connection of the spindle phase compensation constant with the SPD pin. Spindle control signal output. For the connection of sled phase compensation constant. Sled control signal output. Sled feed signal input from the microprocessor.
SL+ JP� I JP+ TGL TOFF TES I I O Tracking gain control signal input from the DSP. Low gain when TGL is "H". Tracking off control signal input from the DSP. Off when TOFF is "H". Outputs the TES signal to the DSP. Tracking signal input from the DSP.
