Finally got my battery compartment in the mail! Had to cut the hard drive case, then arrange
the insides so that everything would fit just right.

It's a close fit!

Got the gain knob drilled and mounted, now for the Volume knob.

Knobs and line in jack assembled.

Wiring up the headphone jack this way lets me cut power to the
speaker when I plug in a set of headphones.

Here is the bare circuit. Once I finish the housing, I'll trim wires to fit the layout a bit better.

Woo! Got the hole for the speaker set, and radiused. Not sure if I am going to leave it
Like this, or lathe out an aluminum bezel. Either way, the grille cloth I have on order
is going to cover the speaker when I'm done.

Several coats of high gloss tung oil, and a slightly enlarged speaker hole.  I also
widened the holes for the control knobs so they would turn more freely, instead of
binding on the smaller diameter hole.
