Providing the manual works fine, quickly and without any problems for an acceptable price. After printing the service manual it took me only a short time to repair my carradio from Clarion. Thank You! Greetings from Heiko

I was searching a way to modify the original phono-in entry (for connection of vynil disc player, with RIAA equalization) to a line-in entry (for connection of modern analog entries, eg. ipod, mp3player).
This service manual gave me the correct hints.
It contains very useful infos for repairing and modifing the hi-fi, such as disassembling instructions, block diagrams, schematic diagrams, PCB prints, replacement parts list.
Very good!

WARNING
Check that exposed parts are acceptably insulated from the supply circuit before returning the repaired instrument to the customer.
CHECKING METHOD
Measure the resistance value between the both poles of attachment cup (power supply plug) and the exposed parts (parts such as covers etc. where the customer can easily touch) and check that the resistance value is 500k ohms or more.
SAFETY PRECAUTIONS
The following precautions should be observed when servicing. Since many parts in the unit have special safety related characteristics, always use genuine HITACHI replacement parts. Especially critical parts in the power circuit block should not be replaced with other makers. Critical parts are marked with a ! in the circuit diagram and printed wiring board. Before returning a repaired unit to the customer, the service technician must thoroughly test the unit to ascertain that it is completely safe to operate without danger of electrical shock.
