Helpd me mont a new carradio when prewius mont was a mess.
 ;
Very good service and quick service, very good quality of service manual!
 ;
Great tape deck manual!
I'm very positively surprised, because it is a very long manual, lot of pages, drawings, diagrams, description of how to make the alignment and adjustment procedures.
It is as good as the old "Naka" manuals from the 1970's - if somebody have seen them, they know what I mean by that.
I recommend to buy this very much !

I am a vintage hifi collector. No way to fix that device without the appropriate service manual...thanks to your site I got it and every thing is easier now. I got the manual right after ordering: fast cheap accurate ... thank you

Wonderful job clear. Qick fantastic. These people are really good. If even a problem arise they are wonderful assisting you. These scheme is so net despite this is a very old TV. Thank you for everything!!!!!!!!

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.
