some photos...

In the view from the back, you can see how the chassis is split up into the upper part, with the tubes and most of the important stuff, and the lower "power bar" where the 120vac wiring goes in.  Also, the low-voltage solid-state circuitry for the footswitch (the relay system) is located inside this lower bar.  The power transformer is mounted on the floor of the case, behind the power bar.  A bundle of cables, visible on the left side of the view, connects the upper and lower chasses.  (There's enough slack in this cable that you can slide out the upper chassis and rest it on the bench next to the amp, with the speaker and power still connected.  This makes it easy to work on and modify.)  Also on the floor of the case, partially visible behind the power bar, there's a little white USB charger plugged into a utility outlet: this is the 5v power supply for the relay system.

That rough-hewn piece of aluminum sheet is a heat-shield; I'll design a nicer curved piece of metal for this, if it seems necessary in the final design.  There may also be a partial cover or grille over the tubes, although I like them being out in the open on my personal amp.  Any covers will be removable, so...

The strip of plexiglass along the back edge of the top, is to keep stuff from sliding off when the amp is tilted back on its little heart stand.  In particular, the stuff might be effects equipment, such as my nanoverb.

You can see that the panel markings do not reflect the latest evolution of the amp: the jacks are labeled "pre out" and "pwr in", but now they are actually "send" and "return".  The distinction is important!  (Mainly a matter of different signal levels.)  And, there's no labeling at all for the three toggle switches on the upper panel, since I added those progressively in the development process.  That's the nature of prototyping, but fortunately I managed to get a usable amp for myself out of it.

The paper label on the top of the amp, has these things correct.

The plywood speaker baffle is a little bit, umm, messed up at the top of the circle, as you see.  More prototyping churn!  It's because I started building the box before I had the speaker in-hand.  Guess what, so-called 6-inch speakers are actually 6.5 inches.  (The bigger ones like 10", 12", etc., are exact as claimed, in outermost diameter.)   So the correct height dimension for the manufactured boxes will be 0.5" greater than this prototype, and the speaker will be centered in the baffle.

This will probably be the minimum set of items which would be included with the amp:

Power cable, guitar cable, footswitch, footswitch cable.

I envision making available some nice piece of luggage which fits the amp and its accessories just right.  Here, then, is a more realistic minimum set of accessories: both the things that would come with the amp, and the additional items necessary for a typical complete setup with digital effects.

 

Ready to play.

The box shows the approximate volume of all the accessories: these two items plus a guitar, is everything needed for tube amp bliss.

Also note that the box is quite necessary, given that I don't have the luggage yet: unlike bigger combo amps, there's really not room to stick stuff in the back of this amp: not even its own power cord.  It's too close to the tubes, and just, nah.  So some kind of bag or box generally wants to go along with the amp.  Just an ergonomic observation.

See the note above, regarding speaker diameter and the height dimension: the height of the manufactured unit will be 0.5" higher than this prototype, so 12" including the stand.

(The two side-pieces of the stand, or the "feet" if you like, are easily-removable with screws, along with the folding "hearts" piece which fits between them.)
