Hello Friends, I made an input balance preamplifier in this post. For this preamplifier, I have used NE5532 IC. But in place of NE5532 IC, you can also use TL072 or 4558D IC. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to PCBWay for manufacturing my PCB. PCBWay are the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil and PCB Assembly Service. Here you get, 100x100mm 2 Layer PCB only at $5, And processing time within 24 hours. And they distribute, worldwide. The more you order, the less price you have to pay.
