Lets Build This Amplifier

Hello guys, in this post I make a 2 band stereo tone control board. In this tone control board, you can control high and low frequency. You can use this tone control with any amplifier for it's low noise distortion. For this tone control I use NE5532 IC. In place of NE5532 IC, you can use 4558D/ TL072 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 www.pcbway.com 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 hour. And they distribute, worldwide. The more you order, the less price you have to pay.

You just need to upload the Gerber File, and select the quantity, color, silkscreen, thickness etc. Then select your country, and shipping method and then Pay. PCBWay will deliver your PCB within 7-10 days.

After one week I have received my PCB. You can see the PCB quality, it's awesome. I have ordered Black PCB. But you can choose your PCB color. PCBWay provide total 9 color solder mask - Green, Blue, Red, Purple, Black, White, Yellow, Matte Black and Matte Green. On PCBWay you can get 100x100mm 2 Layer PCB only at $5. Maximum size PCB you can get 500x1100mm. And maximum Layer is up to 14 Layers. And If you order PCB first time at PCBWay, then you get a $5 discount coupon. So upload your Gerber today and get best quality PCB.

Testing Method After Complete This Amplifier

Check Voltages - Check Audio Output and Audio Input voltage. Here you get no voltages 0.00V. If you get same voltages, then connect this tone control to amplifier.

Power Supply:- For get best performance of this amplifier, you use 12-0-12V 750mA-1A Transformer.
