Note :
All capacitors are in µF unless otherwise noted. pF: µµF
•
50WV or less are not indicated except for electrolytic and
tantalums.
•
All resistors are in ohms.
k = 1000 , M = 1000K
•
Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch : 5 mm
Rating electrical power
•
: nonflammable resistor.
•
: internal component.
•
: panel designation, or adjustment for repair.
•
All variable and adjustable resistors have characteristic curve
B, unless otherwise noted.
•
: earth - ground.
•
: earth - chassis.
•
: no mounted.
Note : The components identified by shading and marked
are critical for safety. Replace only with the
part number specified.
Note : Les composants identifies par une trame et une
marque sont critiques pour la securite.
Ne les remplacer que par une piece portant le
