Circuit Description

This is a Jadis JP-200 tube preamplifier with balanced timbre and strong musical appeal.

1、 Introduction to circuit principle

The left and right channels in the circuit diagram are identical. The l2AX7 used is a small signal audio voltage amplifier tube, which has beautiful voice color and strong gall smell,

It is full parallel two-stage common cathode amplification.

The high-voltage part of the power supply adopts the field effect fast diode rectification, and the sound quality is very close to the biliary rectification effect. Independent power supply reduces mutual interference. There are two power transformers, each responsible for the power supply of one channel. The battery is sufficient.
