Note:
¢ All capacitors are in uF unless otherwise noted.
pF: uuF 50WV or less are not indicated except for
electrolytics and tantalums.
¢ All electrolytics are in 50V unless otherwise specified.
* All resistors are in ohms.
kKQ = 10002, MQ = 1000KQ
* Indication of resistance, which does not have one for
rating electrical power, is as follows.
| Pitch: 5 mm |
| Rating electrical power 1/4W |
» METAL FILM (RN) resistors in 1%, 1/6W unless
otherwise secified.
+ fe}: nonflammable resistor.
+ /\: internal component.
> (_]: panel designation, or adjustment for repair.
* Allvariable and adjustable resistors have characteristic
curve B, unless otherwise noted.
¢ _|_: earth-ground.
* 1: earth-chassis.
