Post subject:  Making Chassis Design Choices

So I have a question: How do people make design choices about the chassis for their amps?

This is a question about esthetics, function, and design. As most people who follow my designs know, I generally take some time with my chassis designs to make something, if not striking, at least purposeful or unique. And I am at a crossroads again while deciding on the chassis materials for my next design.

I posted a question over at my web page last week (concerning wood and metal choices) but I haven't gotten much response. So I am asking folks here. How do you approach the chassis designs for your amps? I'm curious.

There are so may aspects to consider when starting a build. For me, cabinet esthetics of the final design
is certainly as important as any other aspect of the build. Also building equipment for customers or myself,
and having the final product look pleasing, professional, and practical from a circuit and user perspective
gives me a sense of pride.
Sometimes it is needed to be traditional. Sometimes artful. And sometimes inspired by an old rusty copper
fitting that has sat in the corner of the room for long time and suddenly one day, click, the light goes on. Certainly
also it is feelings, inspiration, and the wisdom to know a blue LED belongs in a metal chassis while red, yellow
and orange are "right" in a wood chassis.
All that as well of coarse as -circuit needs, signal paths, emission sources, power requirements, component
weight and size, heat requirements.
Hundreds of traditional looking amps, tubes and tranys on top, caps and res underneath, then one day, solid walnut
wood with all parts inside and little holes in the front to see amp parts threw, with briefcase handle on top and
a beautiful thing is born. Still loving the style Matt.

Hi Matt, well as a novice I would be inclined to follow the lead of others when it comes to function, but aesthetically I'd be
happy to put my own stamp on it. A similar problem arose for me when thinking about how to design my first amp. I had chosen two different brands of transformer, Edcor and Hammond, so if I didn't want the amp to end up looking like a christmas tree I took the decision to paint the Edcors black (might be heresy for some). as sometimes you just have to dispense with the most awkward colour.
