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!!
it is really nice to have peple that are doing such a good work!!!!!

I must admit, I was very skeptical... $4.99 for a 74 page service manual. I've seen some very poorly scanned manuals on the Internet, but this one is VERY good quality! Even when zooming into 500%. Great Deal!

Very good detail, Quick service response. A useful service manual with all details. I recomend this service.

(2) Tracking system check Check the TE waveform at pin 15 on IC1.
If the waveform shown in Figure 50-1 appears and soon after NO DISC appears. ? No "Initialization" is possible, but play is not possible. ? No Yes The tracking servo is not activated. Check the peripheral circuits at pins 14, 15 and 20 on IC1, and CNS1A/B.
Yes
A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 20 on IC1.
"Initialization" is not possible.
Data cannot be read. Check the VCO-PLL system.
