A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.

NOTES ON SCHEMATIC DIAGRAM
� Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with �Fusible� is a fuse type. � Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression �capacitance/withstand voltage� is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type � The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given. � Parts marked with � ! � ( ) are important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set. � The wiring diagram and the PWB drawing may be changed to refect improvements in the design without prior notice. They may differ a little the unit you have.
