This particular unit came in with several faulty components. The latter needs doubling in frequency to 38 KHz in order to restore the suppressed carrier and demodulate the L-R signal. With the digital age, Radio Data System (RDS) enables FM to carry text information such as traffic, weather, and radio station information which can be displayed on the end-user’s device interface. It produces 35 watts per channel into 8 ohms with no more than 0.3 total harmonic distortion. The incoming composite signal is filtered into its three components: the mono audio, the suppressed-carrier difference signal, and the 19 KHz pilot tone. To transmit stereo music, FM is enhanced by stereo multiplexing which carries both L and R audio channel content. The SX-650 was manufactured from 1976 to 1978. ![]() Would appreciate input if this is a good replacement or what a good sub would be for this circuit.Picture posted and circled in green in top left corner. Today Im showcasing a Pioneer SX-650 receiver that came in for restoration. The MAX COLLECTOR CURRENT (IC) spec for the KSC1845 is 0.05 Operating Junction Temperature (Tj): 125 ☌įorward Current Transfer Ratio (hFE), MIN: 200 Maximum Collector Current |Ic max|: 0.1 A ![]() Maximum Collector-Emitter Voltage |Vce|: 30 V Maximum Collector-Base Voltage |Vcb|: 35 V Maximum Collector Power Dissipation (Pc): 0.3 W ![]() I have checked several substitute lists here posted from AK members and I see the KSC1845 listed as the sub.I am not quite sure of this because of the board that it is on and the circuit.Here are the specs for the 2sc732. Seems like just as all was working something else poped up.CATRAFTER helped me with this issues and I thought I had repaired it,I got an intermittent problem with the deempahsis working on one channel only off and on(It would cut in for a while and then would cut out or not come on when shut off and powered back up).After studying the circuit layout Mr tom had sent me I started checking transistors.Well the 2sc732 transistor at H-305was bad.Got a reading of 682 on 1 leg and OL on the other.
