Description

Product Details:

Norway ELECTROMPANIET is a classic preamp circuit.This circuit emphasizes the coordination of power supply and amplification circuit Strong driving force and thick sound Pure A-class amplification, sweet sound The details and sound performance of the instrument are unforgettable.

Circuit structure: After the differential input buffer circuit of the field-effect transistor, it enters the first stage differential amplification circuit and then goes to the second stage buffer circuit Then the main voltage amplification circuit amplifies it Finally, the field-effect transistor push-pull output stage produces audio output.

Multiple uses of current limiting diodes for secondary buffering input in the circuit result in significantly improved sound quality, sweet and durable.

Regardless of cost, components are precisely matched.

Nichicon and ELNA filter electrolytic capacitors The sound quality is guaranteed.

Symmetrical design, high signal-to-noise ratio.

Perfect combination of field-effect transistor and transistor, producing warm and powerful sound.
