Jim Nickelson sent me more pictures of my Li'l Dawg Mutt's progress!
Here's the chassis laid out and marked for drilling/punching.
Then the chassis punched out.
Knobs and such added to the front and to the back. You can see the Mercury Magnetics transformers -- both power and output -- attached.
(Whether or not to order the Mercury's was a big decision for me. They're over a hundred dollars more than the "stock" transformers. But Jim said he liked 'em better so that's what I went with.)
Inside you can see the board all set up.
