Finally, i found one website, where i can download this service manual , and fix my hifi. The service manual is very good, and easy to download and to print.
 ;
Complete and very useful. Could have benefited from a little higher resolution on the schematic and layout diagrams for improved legibility.
;
Great Service Manual, Very Complete, as advertised, Perfect, Thanks!
;
Good quality service manual.It has helped me to fix my FV1800,particularly for replacing the dial cord.The scheme is on A3 format and very readable.Thank.Olivier.

This manual is complete and very readable.It was a great help for my two ICF5800L.The first one had the dial cord broken,and without the service manual it is impossible to replace it.Thank.Olivier.

Ver. 1.1
AC adaptor
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.

� A : B+ Line. � Voltages are dc with respect to ground under no-signal (detuned) conditions. � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Abbreviation CND : Canadian model E32 : 110 � 240 V AC area in E model MX : Mexican model TW : Taiwan model
