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.
