Pot A103 for general volume

[piltous]

Hello,

I built my amp with this board:

TDA7294 2x80W+160W

There is no potentiometer for general volume.

I have one that I can remove from a defect board. It's written A 103 on it....

Can this be use to be connected on the input of the board?

Thanks for your help

Depending on the brand of the pot it can be audio taper 10k version, so should be fine for the volume control.

Regards,
Oleg

Hi OlegSh,

I ordered a couple of 10k (really cheap on ebay, I hope they are quite good...) because I was not able to find any other ref on the pot that I have (an I don't know exactly how to do with the multimeter).
I ordered 6 pins, this one that I have is 3 pin so I don't think it matchs with my needs.

So I will plug few "line-in" on it, 2 x jack 3.5mm and a bluetooth module.

Thanks for your help

You are right about the pot. You need a stereo variant with 6 pins.
Good luck with your build!
