So far I´m a satisfied customer. I have only downloaded "TECHNICS SX-KN470 Service Manual" maybe I will use it later.
Best regards

Good manual. It is complete and of high quality, both text and graphics. The schematics are with the original big size, so it can be viewed or printed without any loss of resulution and sharpness.

We needed a manual quickly...online it was available immediately, at a very low price. We loved the convenience!

Thank You

Note on Printed Wiring Boards: � X : parts extracted from the component side. � Y : parts extracted from the conductor side. � : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A) Note on Schematic Diagrams: � All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums. � All resistors are in � and 1/4 W or less unless otherwise specified. � C : panel designation. Note: Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. Les composants identifiés par une marque 0 sont critiques pour la sécurité. Ne les remplacer que par une piéce por tant le numéro spécifié.
Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.
