I gave the triode mode a go but it was too weak ,so I put it back to UL. The biggest change came when I found some ADZAM 6SL7GT valves from the 50's.

I just built it as it was , I like the sound so I didn't change any parts. I have another one so I might put better caps in it, but that's all .

I use a 100k ALPS pot, which is good for a CD player . When I play vinyl I use a yaqin phono stage.

I found some answers to my question but not all.
Dynaco low Power Amp
if someone wants to help me understand the changes from the original schema.
I'm struggling a bit on the classic scheme but this one, I have trouble.
