Hello everyone,
I'm planning a Le Monstre build using MJ2955/2N3055 output transistors and came across this fantastic 2024 version. The designs and insights shared here are really inspiring!
Would anyone be kind enough to share the Gerber files (or a version compatible with my output pair)? I'm especially looking for a proven layout with good thermal and sonic performance adapted relatively to newer transistors (except 2N3055/MJ2955, I know 2N3055/MJ2955 are classics now), my goal is to put to use my current inventory of these transistors and move to the later most modern versions ones talked about in the thread if needed.
I know there are Gerbers available at the beginning (thanks to Patrick) based on original components, however I do see refined PCB layouts based on more modern component adaptations, really appreciate any help or pointers—thank you in advance!

The original PCB already published is compatible to modern day components.
And we have not tried 3055/2955 for the output stage.
They have lower hfe than the ones mentioned here.

Thanks Patrick! Appreciate it. In that case I should start working in this direction.
Completely agree choice of output stage transistors is not something that may seem optimum in today's scenario, however as I mentioned, I'm open to replace these later with more modern equivalents fitting in the broader requirements better. I have a bunch of 2N3055's/2955s which are "matched", though subjective here- so will refrain mentioning as only/go to criterion for linearity- specially with the transistor choice I have in hand today, so feel like worth trying these out with the first iteration.
I'm sure other options may (rather will) perform better given the feedback from fellow members here, however, I see a room to switch to others fairly quick.
