1pair of IRF240 new amplifier board field effect tube small deck 100W + 100W finished board

 

Details：

Using the original IRF240 MOS tube.

 

Input coupling capacitor using German imports of Weimar capacitors 50V/3.3UF, electrolytic capacitors signal main circuit using imports.

 

Resistor selection of five-ring metal resistor, the main circuit using the accuracy of ± 1% of the five-ring metal film resistor, to ensure a good signal-to-noise ratio of the whole machine.

 

PCB adopts 1.6mm thick double-sided plate, 2.0oz copper thickness, spray tin full process, to ensure the good performance of large and small current through. The PCB quality.

 

The entire circuit board alignment layout is quite rigorous and reasonable, the overall PCB alignment using a point grounding method. This amplifier board work stable and reliable, high output power; sound beautiful and round, the sound field is open. Strong sense of three-dimensional, low-frequency stable and solid and powerful, signal-to-noise ratio is quite excellent, wide dynamic range; clear details, excellent transient response, play a variety of music are coping with ease, in the family playback environment has a very good performance.
