According to the figure, this is a fully symmetrical, full complement, double differential circuit. Firstly, the C401 10μF ordinary electrolytic input capacitor should be replaced by a 4.7μF CBB capacitor; then both ends of the feedback blocking capacitor C403 are added the WIMA 0.1μF capacitor, this would obviously make the sound be more smooth and clear; the second step, for improving the open-loop instructions, motivation level Q404, Q409 should be added 10kΩ collector load resistors R1, R2, while the feedback resistor R424 is connected a 8.3kΩ resistor in series, this can give a more natural sound with better transient, while the gain does not decrease and increase slightly.
