perfect copy, im very satisfied, i was need the diagram over the powersupply and
the copy was very sharp

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.

Wanting to repair a neighbours tape recorder I needed the necessary information, it makes it easier. Although the service manual is described as "Language : English" To my dismay I found that it is entirely written in German, a language I do not understand. At least I now have the schematics which will help of sorts. I may not use this service again due to the laguage difficulty after all when it states English you do not expect it to be entirely in another language.

Sensor board Connect the CNTH to connector E950 on the sensor board. E950 Sensor board CNTH
CNBAR
Connect the FEB3 (ferrite core) to pins 2-8 of the CNPOW.
Connect the CNBAR to connector J2, while holding down the small board mounted with the J2 (to prevent stress on the small board).
Make sure that the CN102 and the CN104 have been securely connected (since they cannot be checked in subsequent processes).
Cut off the PVC sheet by bending it back and forth 2 or 3 times with your hand, while holding down the double-coated adhesive tape affixed to the igniter transformer so the tape cannot come off. Igniter transformer
Install the sensor board after completing the following steps: Make sure that connector E950 has been securely connected then apply the TAP3 (to prevent detachment).
