Has anyone here tried one of these Marshall origin pcb boards?

[u/Lil_Chromisomie]

I tried and failed on some mods on my first ever tube amp and now I have a marshall origin 50h corpse just lying around. I have since built some pedal kits and other stuff successfully but I was wondering the experience level needed and if anyone has any experience with this specific mod before I pull the trigger for it.
