 ;
is part of the manual is very useful for repairing
Here are circuit diagrams
if there is damage, I recommend using this part of the
a complete list of circuit boards and components
 ;
Hello.
This paper enable me, to bring this lovley Scope into Function.
Without this Page, i have no cance to make this finish.

I used for first time this the wheat and am very thanked
;
This manual was exactly what i needed and could not find elsewhere. Price is not too high. Great !
;
ecelent I was reciver the service manual soon I fell so happy very complete 100% positive all by this store tanks atte Luis salazar
SECTION 6 DIAGRAMS
6-1. CIRCUIT BOARDS LOCATION THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this 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. � % : indicates tolerance. � ¢ : internal component. � 2 : nonflammable resistor. � 1 : fusible 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. H : adjustment for repair. Voltages and waveforms 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. Waveforms are taken with a oscilloscope. Circled numbers refer to waveforms. Signal path. J : CD c : DIGITAL OUT
