For the enclosure, Bruce used a readily available plastic and aluminum project box from Radio Shack. This is the same enclosure he used for the LM3875 Chip Amp. The photograph below shows the Tube Preamp and Chip amp together.
Similar to what Mark discovered with this economical (read dirt cheap) tube preamplifier kit is that you get a very quiet preamp that can compete with ones that cost much more. For more information about this project, see Bruce's project page, "Beauty" - A DIY 12AX7 Tube Preamplifier Kit.

That is a neat little project. If you mount the capacitors from the underside of the board, you would be able to have more of the tubes sticking out of the chassis. Good work.
