Pre-Owned. I will be making two of these amplifiers simultaneously but with a few critical component I demonstrated the amplifier on a DIY audio day here in the Netherlands for several hours at pretty high volume and it never ran warm (15-0-15V transformer / 8 ohm speakers) People were really impressed by the sound quality of this small amplifier, especially when taking into account the total cost (25 euro for PCB / heatsink / components) The BPA200 works a lot different than the LM3886 gainclone, it is designed as a bridged/parallel bridged amplifier. Gainclone Amplifier / ICs audio amplifier. My homemade "Gainclone" hifi amplifier I used an old power amp case and rebuilt into a world-class hifi amp for my home studio. After deciding I wanted a bit more power, I did some research and am now going to build a so-called gainclone amp based on the LM3886 chip. LM1875 adalah chip amp kecil yang bagus yang mampu memberikan daya output 25W. I have a nested gainclone in the early stages of simulation and design. This DIY LM3886 amplifier board offers the best performance of any LM3886 chipamp implementation due to the optimized PCB layout. Following that, ofcourse it looks different and the values have to be different too if you are going to feed multiple ICs (BPA200: four ICs) because the design goals are different in priority. F. So it's very good The Gainclone concept is based on the original Kimura-San/47Labs Gaincard design, which takes a “less-is-more” approach, low component count, extremely short signal path etc. Using the higher volts really opens it up, punchy. There are some little further: the power supply, network at output speaker and fuse to protect the spike signal of external devices Each one has the following function. The input filter cap blocks DC from entering the amplifier. " Build an LM1875 gainclone amplifier + Cmoy preamp.
