Alternate Layouts for Mark III Chassis

I have received a Mark III PCB kit from Mr. Mottram, plan to buy transformers and sockets from dynakiparts, and prefer building a chassis for a Mark III amp to buying a chassis with the original Dynaco layout. Are there alternate chassis layouts. I'd appreciate suggestions, comments and criticisms regarding this idea.

I've been designing a layout very similar to the Mark IV with a custom top plate and wooden chassis.[img][/img][img][/img]

this uses a different rectifier tube than normal, but is otherwise a VTA MK3 octal.

Looks nice.

Here are two images of what I have in mind. The overall length would be about 11", the width 7". I'd make the chassis out of a combination of 1/4" Aluminum plate(top & bottom), and a wood frame similar to the last images below. I'm curious about the approximate diameter of the KT 88 tubes.

I haven't quite figured out including images, so here are links to Flickr files:

That would be a really nice layout

I was reading about transformer placement in another forum, one contributor suggests that they should be at 90 degrees to each other. If so, how far apart should they be if they are not at 90 degrees.
