I like the idea of simplifying the box joint.

What tool did you use to cut the notch and finger?

logo and front baffle cut, finished, test fit. Probably the most important
check in a one off.... make sure it all fits and the mounting bolt holes line up.

Everything can be done with minimal hand tools, I hacked it out on a scroll saw
real quick because its there, same for the logo, you can use any thing.

A couple finished pictures, nice amp, it makes cheap P-90's sound
wonderfully acoustic. Getting cleaner too. The chassis logo is a nice
addition, makes the product more complete visually and gives a client
another opportunity to have a "your name here". The wrapper is a fabric
foe tweed print. Nearly any fabric can be used, which makes any quilter's
pattern and print accessible. On the inside, nearly any assembly practice
can work too, terminal, point, eyelet board, pcb. The total build budget
fits nicely into about 3 to 4 times the cost of the transformers. $475-$650.
Every fabrication solution bring it closer to a consumer product and transition
away from a "hobby". Not bad for one day circuit dress, and two days to finish.

Its very simple and looks great executed in hardwood.
Bingo! That's also how I make my cabs - heck of a lot easier than finger jointing, and they come out really strong too. Altho' it does take some care drilling a dowel-sized hole that close to the edge of the timber, but its worth it.

The back .... the cab and chassis came out clean.

old GE 6BQ5, very nice. inverter is side getter RCA 12AU7, the EF86 has lost it's marks,.
It has diamond mesh for it's anode. Its very quiet, the bypass values are small
The first fire up had a 25Uf bypass on the EF86 as per the Vox pre, and
the blow was too much. The inverter has an un-bypassed common cathode resistor,
and the shared cathode resistor of the 6BQ5 is bypassed with a Jensen
oil and foil cap, the clean tone is incredible, wonderfully mature.
Simply swapping out the inverter tube changes the nature of the appliance.
12.... at, au, av, ay, ax, bh...7 and 5751 all work to effect.
