Chassis Layout for preamp

[Blair]

After discussin some options with Eric the other day, I think this plan will come together nicely. I have been tinkering with this chassis I got for free from a friend, and trying to think out options since it has some unusual holes drilled in it. The 6SN7 fits perfectly in the holes in the back and if mounted where I gan get a grip on the glass, will be able to be changed without pulling the top plate. I was wondering if anyone might have any suggestions about this layout. Is this OK? The tubes will be mounted to another piece of aluminum to act as a heat shield.





Thanks!
