PCB size: 160X76X2MM

Features:

Fully symmetrical from input to output.

There is no even-order distortion.

Symmetrical Power supply startup and shutdown, will not hear a “popping” sound .

Full discrete components.

The circuit uses dual FET fully differential input stage is fully balanced, the operating current of eachtube 1MA, the entire input stage current reaches 4MA, and maintained in a pure Class A operation, has the characteristics of high input impedance and low noise.

Voltage amplifier stage is also a standard Class A amplification, operating current 14MA.

Complementary push-pull output stage is followed by the design, and the use of high-currentMJE15032,15033G tube! Can get a good impetus to the current adjusted each tube 120MA.

With high PSRR (power supply rejection ratio).

DC servo circuit, ensure that no DC output protection headphones, headphone special protection packagecoupled with E12, so sit back and relax your headphones!
