You may have the same or similar circuit there but as you realise, component types and the PCB layout are quite different, despite using comparable values and parts types. To use this copied design and through-hole PCB, check out how it performed, if you can. If sound quality is important to you, read a trustworthy comparison with the original product before assuming it will do what you want and sound as you like.
A schematic alone is a start but there is usually a long way to go before you have a comparable clone. It think it will need more work to be useful, IMV.
