Today I made my final decisions about which piece of wood would go in each position and orientation. This amp chassis is going to be a work of art!

Actually I made another decision as well concerning the overall chassis dimensions. I decided to make the chassis 3-1/2″ (89mm) tall instead of 3″ (76mm). The extra height serves both to show off more of the spalted alder grain and to provide a little move vertical room inside the chassis. I specifically wanted this extra room for the main filter choke, a Triad C-14X, which goes inside the chassis under the power transformer.

So here are the different views of the chassis. This is just the four boards stood on their sides so you can get a feel for what it will look like. No openings or joints have been cut yet. First the front.

This is the most striking of all the grain patterns. This is definitely the best side for visual interest.

The following are the views of the sides. I took these photos at an angle to highlight how the grain pattern in the front will flow into the sides when looking at the amp from an angle. First the right side.

And the left side.

The sides have some more linear grain elements than the front. I like the way these almost look like they are pulling the grain from the front backwards. I think the overall effect is fairly unique.

And finally, here is the rear piece.

This is the most linear spalting grain and the least visually interesting of the four. However, because there will be two long narrow openings in the back, I think the linear grain will work well as an accent to the rear plates.

This chassis will get no stain or any coloration. Just several coats of oil to bring out the natural color of the wood and all that beautiful spalting. Over the next few days I’ll get all the joints and openings cut and get the chassis put together. After that comes finishing and cutting all the metal. It should be a busy week.

As always, questions and comments are welcome.
