BOOOLE HIFI stereo LM3886 full DC servo amplifier board 0HZ superior Shen Gang line with elements Golden Edition

Kit does not contain aluminum radiator and the main capacitor

This circuit kit parts, needs its own welding debugging. Require welding debugging plus $ 6

 

LM3886 DC servo circuit board added, canceled the effects of the Voice of the coupling capacitor and feedback capacitor circuit phase distortion, transient distortion significantly improved response 0HZ-100KZ pretty straight, airy, detail, location is very good, the midpoint voltage also more stable

PCB size: 96X86mm

Circuit output power: 68WX2 8 Europe, output drive current 10AX2

 

Voltage range: AC12X2 to AC28X2 recommended value (18X2 to 26X2)

National Semiconductor LM3886 Overture is the top model in the series, the sound warm and charming, low-frequency fullness, Naiting natural, better than the TDA7293 the actual audition is not small. At full power, TDA7293 distortion is several times larger than the LM3886.

Full DC servo circuit better than any one of the LM3886 circuit

Confidence 2 with full-function protection circuit. Power against shock, output short circuit, DC protection, use, after all speakers many times more expensive than the amplifier, using Omron Japan UPC1237 +

3 compact board design, layout and reasonable ease of installation, the diameter of the main capacitor can install 20MM to 35MM

4-element close to perfect, US Army regulations resistors, Germany ERO etc.
