Hi Team,
I am looking to build class D amp TPA3251/TPA3255 and searched threads for Gerber files. not found any.
But Chipdipru has creative common license.
GitHub - chipdipru/RDC2-0034-TPA3255-classD-amplifier: Усилитель мощности класса D. TPA3255, PurePath, 315Вт Stereo или 600Вт Mono.
GitHub - chipdipru/LCF05: 2nd Order L-C Output Filter for Class D amplifier
any thoughts on this. My soldering skills are very basic never tried smd parts.
Initially I thought buy from aliexpress but previously I had strange experience with ESS2098Q2M board noisy.
So this time I am thinking to build my self. need 30W to 40W clean output each channel.
Please let us know your guidance on this.
Thanks,
Nag

The layout of this PCB is awful to me...
I have one bundle at home, waiting for Rigol DS1054Z to arrive to me next week to test the amp and to open a thread about it.
Here is mine:
My heatsink is from a Gigabyte PC mainboard and I use small fan, not shown in the picture.

Hi DZWER,
Thanks for the pic. As per the chipdip we can use it with 4 channels using capacitors in output path. Do you have any knowledge about it. Is it will imapct any sound quality.
I am planning to clone lxmini so need 4 channels with 30W-40W each channel.
Thanks,
Nag.

Of course it will impact the sound quality! You can try to solder some MKP capacitors in parallel of the output electrolytic capacitors, when in SE configuration.
For 30-40W you can use TPA3116 instead of TPA3255.
