What to check before buying used
On an amplifier of this class, it is worth checking the condition of the volume and balance potentiometers, which can develop crackling after several years of use. Checking the input and output RCA connectors ensures there is no play or oxidation that would affect signal quality. Ventilation and heat build-up at full power also deserve attention, as Class A/B generates more heat than a Class D stage.
