ONKYO T-4970
Service Manual

This is exactly the service manual I needed. Complete with all schematics, partslists, PCB layouts and alignment instructions. This manual covers both the T-4970 en T-488F Onkyo tuner.

This is the 2nd time I download manuals from this website and I can say it's what I was expecting. It contains schematic, layout (decent quality), short description, parts and dissasembly instructions. I recomend it for anyone who wants to repair/modify this device.

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!

Incredibly clear!!!! Well done, complete and wonderful. It could not better than this!!!!

Thank You for fast delivery for the sheme. Everything allright. Thanks & best regards Franz

again you did a very good job. It was fast too. Photocopy are really readable and clear

Probably it never existed a 1081 official service manual from Commodore, it's look more like a NAPCEC service manual & diagrams compilation of the 1084 series and his variants, like the nap6523, 8cm505, 1084S, 1084P and obviously the 1081. It's more complete than other scans and the quality of the scans also are far superior. It has two circuit diagrams variants of the 1081, mono and stereo versions. It doesn't include a diagram for the Philips CM8500 or CM8501, they look like the 1081 but they are slightly different.
