This manual was the factory original. Excellent value and contained all the details I needed. Easy dowwnload provided the information when I needed it.
;
Impeccable, document très complet. Perfect, i get all i need. All schematic are correct. Thanks

The manual is of better quality compared to other. I found it less expensive and therefore it it is the best buy cost vs quality.

I bought the service-manual of the sony ICB-1020(an old transmitter-receiver) at "www.Owners-Manual.com", I found the service-manual for a fairly cheap price(in comparison with other sellers). I filled in some questions, payed the order with Ideal, and within 24 hours I had my service manual. I was very happy:In no time I had my service-manual and everything, but literally everything was noted down in the manual; the electronic scheme, the parts list, etcetera.
A very practical, reference-document.

This comprehesive service maual was greatly appreciated, as was the digital download.

1) Focus error amplifier unit
This focus error amplifier outputs photodetector output (A + C) or (B + D) from pin 16 of IC201 (TA2150FN) via a differential amplifier and an error amplifier assuming (A + C - B -C) as an FE signal. The low frequency component of voltage FE is expressed as FE = (A + C - B - D) � (150 k / 62 k) � (60 k / 60 k) � (12 k / 60 k) = 4.84 times. An S curve of approximately 1.45 Vpp is obtained in the FE output on the basis of Vref. The cutoff frequency is 26 kHz or 133 kHz.

2) Tracking error amplifier unit
This tracking error amplifier unit outputs photodetector output E or F from pin 14 of IC201 (TA2150FN)via an amplifier and an error amplifier assuming (E - F) as a TE signal. The low frequency component of voltage TE is expressed as TE = (E - F) � 300 k / 100 k � 155 k / 328 k � 82 k / 20 k = 5.8 times. A TE waveform of approximately 1.51 Vpp is obtained in the TE output on the basis of Vref. The cutoff frequency is 44.5 kHz or 29.4 kHz.
