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!

Great Job!!! clear and efficient as always!!
