Question about Marantz 7 circuit

Posted by Tube747 on February 3, 2025 at 03:37:48:

I found a very interesting article about simplified Marantz line amplifier.

https://ttradio.net/clone-marantz-7-m7-line-amp/

Here is what my friend simplified based on the Marantz 7 diagram, so which one should I go for? The one from ttradio or one from my friend?

Please advice!!
