The Gainclone was based around a cheap power IC, which is typically fitted to TV sets, portable stereo systems and cheap surround sound amplifiers. Dual Japanese OMRON protection circuit, so that the expensive sound box work in a safe state, the switch is also no impact. LM3886 amp boards (left) and power supply (right) There are apparently a lot of shady sellers on ebay selling chip amp kits out of east Asia with counterfeit chips and low quality construction. tda2030 amplifier circuit 12v TDA2030A audio Power amplifier circuit, often uses V-type 5-pin single in-line plastic packaging structure. 100% brand new and high quality LM3886 is a single-channel, high-performance audio power amplifier IC produced by National Semiconductor (NS) company , the maximum continuous output power up to 60W, from the lauched time to now, was loved by the majority of audiophiles. DIY HiFi Gainclone Power Amplifier (2x68w, Class AB-A, LM3886): I've made gainclone amplifier that uses a LM3886 chip. The result is clear sound without any static, pop or hiss. Most people would say the NatP is a more refined design. Analog controlled class D is the way to go in the future. This new version has PCBs available, and its performance is as good or better than the best commercial offerings around. Shortly thereafter Yoshi Segoshi of Sakura Systems responded, claiming that the photos were not of a 47 Labs Gaincard and when asked to provide photos of the internals of a real Gaincard, he refused to do so. A plain-vanilla single-chip chipamp like the LM3886 and TDA7294 are capable of serious audio and sub-Rs. The box is a wooden wine box. I figure I might as well build it properly the first time. The Audio Sector GainClone offers a sound redolent of the beauty of open heart surgery. Several solid-state designs emerged in the 70s but it was the all tube D70 in 1983 that established forever the hallmark “high definition” sound of an Audio Research amplifier. The price is high and there is no impact on the boot. With equal loudness switch, this small volume is more full of natural. Full-Range Sound for Keyboards and Electronic Musical Instruments The KC-80 offers full-range audio reproduction in an easy-to-carry portable amp. Re: mtm with best sound quality ? The BAMTM is simple and cheap. The LM3886 is one of the most highly regarded audio chip amplifiers in the DIY community. Dual mono pcb design to ensure best channel separation Design with separated amplifier and power supply pcb to minimize noise pick-up. From testing the prototype boards, I was a little more critical of everything. Excellent sound quality from well-known amplifier ICs. Bluebook The right price. The reason for its popularity is due to its very low distortion, minimal external components, and low cost. Arduino Powered Gainclone (amplifier): For those of you that do not know (and I didn't until recently), a Gainclone is an amp that is a 'clone' of the original design of an amp made by 47 Labs called a Gaincard and are based on single chip amplifiers made by National Semiconductor - Na. Flat brown big stamp size ones are ceramic capacitors and resistor compinations. As it's a second system, not looking for any exotic/expensive components, just want to make best choice of sensibly priced options, while trying to achieve as good a sound quality as reasonably possible. Overall, I powered the circuit off of 6 volts, which is on the low end of the possible 5. It is a Class AB-A (conjugate) amplifier that has a fully symmetrical structure (push-pull), this mean that the sine waves produced, will produc. Yes, the LM3886 can deliver about 40-45 watts into 8 ohms.
