I think you should read and follow this thread:

Are you ready to face strong emotions?.. Dx Blame MKII and the Supercharged release!

Good start was Blame ST and here it is, Blame-ST-TMC.
Voltage is +-40V a bit more and the feedback resistance a 22k/820 same ratio but higher input resistance. PCB hand made.
The loudspeakers are hand made Seas woofer and mid/high ribon by Newform Research.
I like the sound of the combination very much.
Here is schematic and LTSpice simulation.
hi dadod, can you share your pcb design

Dadod. Have you heard of a place called Oroslavje?

It absolutely is worth the addition of 4 pads (2 components) which can be omitted/ jumpered for traditional compensation. I do it like (below) , the PCB reflects this as well.

Hi Dacuycoy,
PCB is very similar to original DX blame, just TMC possibility added, and feedback takeout point changed a bit according to Self.

He is really away for a while, and I am not his representative. I only try to help, since I built this amp twice and know these obvious things.
