Product Details:
Refer to the Accuphase 3850 amplifier circuit.
The circuit architecture is the operational amplifier as the basic amplifier, discrete parts are added to increase the open loop gain, and the voltage and current dual feedback circuit is used to reduce distortion. The output transistor uses the original British ZTX450 ZTX550, and the class A state output.
Use Philips NE5534 for input amplification, A core oxygen-free copper transformer.
Use ALPS27 potentiometer, American CMC816 24K gold-plated RCA input terminal.
3 input options, no need to plug and unplug the power supply.
All aluminum chassis is used.
