Most of the parts are mounted to the top plate. Here the plate with the sockets, power transformers and one of the chokes:
The sockets of the signal tubes are mounted with vibration damping rubber pieces:

Some comments about the sound from the first user of this phono preamplifier:
This preamp has absolutely no hum in my system. What is remarkable is also the absence of any other noise. It is just as quiet as the transistor phono stage which I was using before which got praise for it's low noise. The sound stage is first class which is important for me since a lack of sound stage would be immediately apparent through my electrostatic speakers. Everything is at the right place and the sound stage extends well outside of the speakers. The music is very powerful. This preamp sounds very relaxed and enjoyable both at high and low listening levels. I have found 'my' phono stage.
