Product Description:
Thick film STK3048 push three Ken SAP16N / P amplifier circuit, as the 90's gold plaything, its tone pure, transparent, large dynamic performance freely, small signal when the delicate sound is slim, small distortion, etc. is very characteristic of the time by a lot of audiophiles and the pursuit of.
Sanken SAP16N / P for the single in-line five-pin package, the new audio high-power pairs of tubes, the output current of 15A, withstand voltage of 160V, power 150W, the transistor built-in temperature compensation diode array, to solve the amplifier circuit in the temperature compensation delay in the technical difficulties, it's the temperature compensation pole is placed in the center of the transistor chip, can quickly and synchronously detect the change in the temperature of the transistor and correct the bias current, so that it can be used in a variety of applications. The bias current is corrected to keep it constant.
Circuit features:
● Classic thick film combination STK3048 pushes SAP16N/P
● DC midpoint voltage servo with almost zero midpoint voltage
● Current-type negative feedback
Original chemical decoupling capacitors
High-performance op-amp feedback volume control circuit, eliminating the influence of resistor potentiometers.
● Static current can be arbitrarily adjusted according to the situation.
