jeff rowland dual LM3886TF amplifier mono amplifier board lm3886 amplifier diy kit (need weld yourself ) Wu Gang LM3886 Features Description: Produced LM3886 friends generally know 3886 was undoubtedly the best-sounding Gang circuit on the circuit and AUDION DIY circuit, the former is National Semiconductor nineties hold prize-winning circuit, sound natural Needless to say, the dynamic response is very good, mainly due to the impedance of the speaker into the feedback loop,Speaker load impedance is dynamic, so that the amplifier can be a good dynamic response with the speaker changes, mainly through 0.22R/5W this resistors,This resistance and sound related, so choose Japan imported non-inductive resistor, temperature drift and stability are very good! On the latter AUDION DIY LM3886 Circuit sound quality is also very good, mainly the feedback loop is very deep, so it also brings stability losses and the generation of self-excited, but the wiring reasonable, These can be overcome; identification of both the owner still like Gang circuit, having listened to a few years or a soft spot for this circuit. Technical parameters: Output Power: Maximum power without distortion 120W . Speaker Impedance: 4-8 ohm impedance speakers can be connected. PCB size: 51MM * 94MM * 1.6 double-sided sheet KB Supply voltage: DC dual 24V-42V, recommended dual 35V (note not double 35V transformer, is plus or minus 35V DC, recommended dual 26V/200W These toroidal transformer, rectified DC voltage of about dual 35V) reminder: LM3886 high voltage when the sound is much better than the low voltage. Material Introduction: 1. All resistors are 1% precision metal film resistors (in addition to a 5% accuracy 8.2R/1W as well as two non-inductive resistor 0.1R/5W outside), using a P hilip brand CBB capacitor, electrolytic capacitor is the new import Nippon. coupling capacitance as a dedicated audio film capacitors 3.3uF/400V, beautiful sound, bass, pure! 2. New import LM3886TF National Semiconductor Amplifier IC! LM3886TF of plastic and heat sink without additional insulation sheet. 3. Two parallel that two new imported LM3886 portfolio relatively speaking with a single chip is a single-channel amplifier, but the effect is a significant difference, especially in the low-impedance speakers when pushed to better reflect it, because two parallel can output more large current, the effect is very easy to distinguish. National Semiconductor LM3886 is a series in the high model, sounds warm and charming, low-frequency fullness, Naiting natural, like the voice of a friend can be used with LM3886 preamp to push the floor boxes. Product pictures: PCB board silkscreen with component values are very convenient DIY 3Pin is DC power input terminals: -VCC GND +VCC select Dual 20-42V AC voltage. recommended dual 35V Environmental green 2Pin 5mm is input terminals: GND IN , Audio input connection 2Pin 8.255mm terminal are output terminal, OUT+ OUT- Directly to the speaker NS LM3886TF Laser engraving fonts Overall nice, LM3886 performance and sound quality are very good, after all, this line came two decades, it is Many fans have commented on the sound quality than the official website of the line to be nice a lot! Compact, inexpensive 3886 board for diy amplifier board after the class Board needs to work with a heatsink, please remember that the link does not include the heat sink The Installation image for reference Circuit design for reference
