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.

CIRCUIT OPERATION
1-3) PB MODE
When playing the tape, the signal which is picked up from the tape is amplified 50 dB. Then luminance signal goes to pin 11 and color signal goes to pin 7 through AGC. Luminance signal of pin 11 is input to pin 39 of IC301 through PB EQ circuit in order to match playback characteristic. Color signal which is output from pin 7 of IC401 is input to pin 15 of IC301. PB FM signal is demodulated by IC internal demodulator then it is input to pin 3 after MAIN DE-Emphasis process. If this output signal has burst, color component will be separated by X303. If it has burst, it is input to pin 4 of IC301 through Yemphasis circuit. The signal which is input to pin 4 is output from pin 12 through 3.5M LPF, then it is input to pin 10 through 1H CCD. Color signal which is input to pin 15 passes ACC in order to stabilize level, then 3.58H components will be extracted by 3.58M BPF through Main Converter. This 3.58M color signal is input to pin 25 of IC301 in order to eliminate crosstalk, then it will be mixed with luminance signal after passing CNR circuit. Finally Y/C composite video signal is output from pin 34.
