Note on Printed Wiring Board: � Y : parts extracted from the conductor side. � r : Through hole. � b : Pattern from the side which enables seeing. (The other layer�s patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A) 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.

Note on Schematic Diagram: � 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. � U : B+ Line. � Power voltage is dc 14.4V and fed with regulated dc power supply from +12V and REMOTE terminals. � Voltage is dc with respect to ground under no-signal condition. � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances.
