Description

Introduction:

This preamp is reference is from the  Accuphase C3850 circuit  .it is worth making and admiring preamp circuit. If you do it carefully, the effect is much better than the general pre-stage. It is looser, more delicate, warmer and charming, much better than Ordinary tube and op preamp.


The circuit architecture uses 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 tube uses the British original famous tube ZTX450 ZTX550, and the output is in Class A status. The music tastes very good.
