Hi @james_n,
You can’t beat an internal photo 
We haven’t release internal photos today…here’s some hot from the R&D bench for you! (excuse the blurred iPhone photos!)
All inputs are reed relay selected, the vintage buttons operate logic circuits rather than switch the audio directly. Much better for sound quality, x-talk and long life. The ‘thunck-ring’ sound of pressing the input select buttons has been replicated for that authentic feel.
ALPs blue velvet volume control
Discrete transistor MM phono stage, design exclusively for the Nait 50. The RIAA EQ of the Nait one was replicated in the new circuit.
…also has auto-off music-sensing, soft-start and 0.5W standby
Cheers
Steve
