"This Koa board was given to me as a rather smallish thing @13''x 3" x 2 1/4", so I cut it up into 1/8" veneer and glued it bookmatched for this box with some shop scraps of Maple and Mahogany thrown in to sweeten the sauce…"
"Yes, it is my adaptation of it though. The original Bazz Fuss was designed for bass guitar with a different transistor, diode, and input cap. So, through some experimentation I changed the input cap to work much better for guitar. …"

http://uniontownlabs.org/tools/stave/ has a free stave calculator to get the angles and sizes. After the glue dries I cut the inside with a trim router with a bowl bit and the outside with a larger router and bowl bit. Don't forget to cut your snare bed- I use a straight router bit for that. You will need to make sure that the bottom and top of you drums are square then cut the bearing edge with a 45 degree router bit on the inside. outside I use a round over bit. Hardware is available on Amazon and other places. Takes lots of sanding and finishing can be a pain but it is fun. Good luck!
Fair to say no, havent made a tube amp yet. I understand the dangers of the high voltages, and have seen both the doberman amp gear like ax81 and champ schems. I will keep looking and researching, and appreciate your time. Take care.
Thanks Andrew. My focus is low watt amps, as you have done, in the under-5 watt class. I have made many of the solid state LM386 circuits to fit into cigar boxes, and at 1/2 watt (well, actually 325mW) these are quite alright. I make these in "combo" form with a speaker in the box, with an added switch and "line-out" jack to enable connecting to an external cab. I have a pair of older stereo speakers, each house a 12" field coil speaker rated for 50 watts at 8 ohms each, and have converted one to connect the LM386 amp...makes for a great full sound which makes the amp seem much bigger than it really is.
There is a local electronics shop here( a very old school gentleman who owns/operates), and can likely find the obscure tubes there or find them on Ebay. The video showing the use of wallwart transformers fascinated me. Ultimately, I don't want to enclose the amp circuit in a cigar box...rather, to make my own small custom one-off wooden enclosures in a "head" form like yours, since i like the versatility of connecting the amp to different speaker cabs to readily match the amp with a good sounding speaker.
Sound I prefer is clean-ish with reverb and a bit of crunch when pushed, which I get from the LM386.
Anyway, I appreciate any info you may be able to offer.
