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.

As Always you can find here manuals even of difficult TV scheme which are scan in almost perfect way.clear and fast!!!!!
Great work thanks!
3.2 Check the B/E microprocessor
Are the +3.3V_D1 and +2.5V_D2 of Q102 voltage lines normal? OK
NG
Check the soldering of Q117 and Q116, and the input/output voltage. NG OK Input voltage is OK: Check the soldering of circumference components of Q102. Soldering is OK: Replace Q117 or Q116. Refer to �1. POWER SUPPLY PCB�.
Is the clock waveform of 18pin on Q102 normal? (27MHz. 2Vp-p) OK
NG
Check the waveform of 4pin on Q105. (27MHz 2Vp-p) NG OK Check the soldering of R168 and R153. Check the soldering of X101, circumference components and Q105.
