5 STARS for FAST DELIVERY, BEST PRICES and QUALITY PRODUCT. Item was exactly as described with superb resolution. Will definitely source all my future requirements from this website. Thanks a lot owner-manual.com!
;
OEM manual provided all schematics, board layouts and component specs necessary to facilitate unit maintenance. All pages were clear and readable.
;
Good condition and quality. Hard to find anywhere in Internet, only on this site.
 ;
Exactly what I needed to be able to bring the amp back to life... will come back to this site the next time I need schematics.
;
Information was accurate and very helpful.
However the continuity made it a little difficult to follow from one page to the next.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) For schematic diagrams.
Note: � 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. � ¢ : internal component. � 2 : nonflammable resistor. � C : panel designation. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. � U : B+ Line. � V : B� Line. � Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM
� Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. � Circled numbers refer to waveforms. � Signal path. F : FM
For printed wiring boards.
Note: � X : parts extracted from the component side. � b : Pattern of the conductor side. Caution: Pattern face side: (Conductor Side) Parts face side: (Component Side) 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.
