At first I thought Tom might have gotten some bad weed as C904 A & B are shown wired in parallel and I don't know what a 15K cap would be. The schematic is obviously in error.
R602, a 15K resistor is probably between the two sections but according to the schematic R602 is shorted out by a connection between points shown as 21 and 7. So Tom is correct and the schematic is not! If we assume Sony didn't put a resistor in there and then short it out we have the 470 mfd filtering the incoming DC and the 10 mfd on the base of Q801, probably to reduce noise.
