1、PAGE 1-01-01 NAD C160/C300/C320 Modification PROBLEM: You may receive a complaint where the unit keeps some or all inputs active. As a result the output signal constists of several different input signals all at once. CAUSE: A leaky capacitor in the input selection circuit keeps the input active. SO

2、LUTION: Change the following capacitors from 10nF/50V to 10nF/100V C160: C1, C5, C6, C506, C507, C508, C509, C510, C511, C512, C754 C300: C112, C212, C509, C708, C723, C724 C320: C1, C2, C4, C5, C6, C57, C514, C515, C516, C517, C518, C519, C520 PRODUCTION: This modification will be implemented into production from serial: H04C16002191 H04C30009750 H04C32026880 RadioFans.CN 收音机爱 好者资料库
