Korg Nutube 6P1 vs 12AU7 tube: Hybrid Amplifier (1)

My next project is an Hybrid guitar amplifier: Triode preamp + Class D 25W amplifier.
FreeCAD 3D files can be found here:
https://github.com/Rezzonics/NuTubeAmp

The preamp section can be populated with a Korg Nutube 6P1 triode
 or alternatively a 12AU7 tube
The amp is powered by an external AC/DC 24VDC out wall adapter.
It includes headphones, line out and 8 Ω speaker with 25W output.
Everyting is packed on a compact 1590J enclosure:

    I'm really interested in your design here especially with a Nutube. Would you be using the pre-made Nutube carrier PCB, or just doing the whole thing with one board, no daughterboard?

    I added no daughterboard, I may add a socket though the pins are maybe too wide. The NuTube will sit over two rubber bumpers placed below it, hopefully that is enough, will see.
