Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.
Detailed SONY CFD980 Service Manual at an easy to find one stop shopping. Make my radio hobby technically interesting. Thanks.

SRS-Z510 SECTION 2 DIAGRAMS
Note on Schematic Diagrams: � All capacitors are in µF unless otherwise noted. pF: µµF 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. � A : B+ Line. � Power voltage is dc 9V and fed with regulated dc power supply from DC IN 9V jack (JK4). � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Signal path. F : AUDIO Note on Printed Wiring Boards: � Y : parts extracted from the conductor side. � b : Pattern from the side which enables seeing.
