4. When the amp is turned on, don’t short the output, press class A and class AB switch, or plug in and out signal cable.FeaturesInspired by Accuphase A35 circuit and E650, adopting 3 pairs of US IRFP240/9240 power transistors in each channel, for larger current which can reach 20A.When working in class A, the sound is more detailed, the high and low frequencies extend well, and the bass control is very good. In Class AB, speed is faster and the high and low frequencies are cleaner. Specially designed and adding higher playability for audiophiles.Using 30A imported relay, with class A and class AB status switch, providing differnt working styles to choose.High-end and good-quality components are used, such as 16PCS Nikon55620uF filter capacitor in each channel, Italy AV MKP film coupling capacitors, 350W iron-core toroidal transformer, imported capacitors and resistors, 35A bridge rectifiers and 30A relay, 2.5KG heat-sink fin and so on.All-aluminum precision chassis, surrounded by large mesh cooling.
