Great news for the headphone DIY community; Pete Millett has released his Sengaku design as a DIY friendly offering on his site: http://www.pmillett.com/sangakuDIY.html
The original was a TTVJ offering in 2016 for $2K. Changes include swapping SMD for through-hole components and ditching the fancy selector switches on the front.
You can snag the bare bones kit on ebay for $170 + shipping which includes the board, two Nutubes, two flexible mount systems (NuTubes are fussy about vibration), and two JFETS, which I assume are matched.
Below is the populated board.
Well-documented DIY balanced tube amp projects are like hens teeth. Other than the Bottlehead Mainline I can't think of any others. It would be nice to see Elekit start offering balanced headphone outputs as their latest 300B / 2A3 amps are very well designed.
This should be a high performing design. I'd imagine swapping out the coupling caps, potentiometer and using discrete op-amps will take it to the next level if you wallet can handle it. If not it will still be a tremendous value.
I have my kit ordered. Let me know if you plan to build one as well. Gotta keep this forum on life support
For anyone wondering I believe the output should be about 1 to 1.4W in 32 ohms.
