Heres some photos to get you started.
Not exactly a scratch build, but an Asymetrical approach to a nice looking stereo SE amp that was made with what I had to work with from an old Magnavox.
Here is my own chassis design for a Dynaco ST35 clone.
I used a hammond 12x10x2 aluminum chassis and polished it using metal polish available at Lowes hardware. I used cheap 1x2 oak craft strips from Lowes for the casing at a total cost of $3.50. The control knobs for both are $1.75 at radio shack, and look quite professional and "hifi" IMHO. I like to do things on a budjet, so thats my take on things. Hope you're inspired!

An externally hosted image should be here but it was not working when we last tested it.

Beautiful work! I notice that you didn't show the guts though.
Have a look at the stuff that VT4C is selling. There are knobs, chassis and "collars" (or plates) that are attached to the tube sockets. You will also fine nice retry type meters.
Go for a solid wood chassis of beech or birch or oak. Use some kind of oil and work hard to get a nice surface.

there is the stuff I used, I don't know if theres a name brand but it is made in the USA. You can find it in the tool section of Lowes. I only used the high gloss stuff so it took a while to polish it up. Its basically a claybar that removes aluminum and smooths it out while polishing at the same time. Messy and you must use a buffer or drill with a small buffing wheel.
Thanks dubdub, that was the magnavox shield off of the radio that the amp came out of. Thought it gave it that "botique-im some-high-falutin'-fancy-brand-transformer" type of look
FWIW, the transformers are made by Stancor as indicated by the 138 IEA code on them.
