Hello guys, I make a 5 band stereo tone control board in this post. In this tone control board, you can control high, mid-high, mid, mid-low, and low frequency. You can use this tone control with any amplifier for its low noise distortion. I use TL084 IC has a 4-channel OP-AMP for this tone control. 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.
You must upload the Gerber File and select the quantity, color, silkscreen, thickness, etc. Then choose your country, and shipping method, and then Pay. PCBWay will deliver your PCB within 7-10 days.
After one week I received my PCB. You can see the PCB quality, it's awesome. I ordered White PCB. But you can choose your PCB color. PCBWay provides 9 color solder masks - 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. The maximum Layer is up to 14 Layers. If you order PCB for the first time at PCBWay, you get a $5 discount coupon. So upload your Gerber today and get the best quality PCB.

Check Voltages:- Check Audio Output and Audio Input voltage. Here you get no voltages 0.00V. If you get same voltages, then connect this preamplifier to amplifier.
Power Supply:- Recommended Transformer 12-0-12V 750mA to 1A.
