Hello sneha,

Dont go with any pcb design.

So much people are uploading bad design.
So much errors and all,
Just sir mile( apex audio) designs are tested himself...so you can use it with trust......🥃🥃🥃🥃
I suggest you to make your own pcb design...
Btw, come soon back,

 

[NMOS]

I agree 100 %

thats why I have design myself Class D UcD PCB from schematic Mr. Kartino

Dont think its easy like class AB/H,

also you need PCB design software to proof PCB routing mistakes V/S schematic otherwise sure you will get first time smoke

Be aware to buy amplifier PCB from 3th party, make it self

I losing time and money, and be aware to buy IR Mosfet driver, Power Transistor in epay if you design amplifier

buy from mouser, digikey, farnell, tme, lcsc and you will have working amplifier
