For a first project, keep things simple! I think you could skip L1, U3, C2, R2. Make R7 a 4K/10W resistor from ground to the remaining cathode follower, then cap couple the output through a 220uF/250V cap with a 1K resistor from the output of the cap to ground.
The K701 looks like it will be ear bleedingly loud with about 1V delivered to the headphones. 1V into 62 ohms isn't a lot of current, so the step-down transformer may be a bit overkill. The output impedance of a 6E5P cathode follower ought to be sufficient for this to work nicely overall.
(The circuit you designed may sound a lot better!)

I was wrong about the first project. I've already built a huge number of tube amps. But this is my first Headphone amp. I like to complicate.
Thx for your opinion.
Looks overcomplicated indeed.
Single triode-strapped 6E5P with 5-7k OPT is perfectly capable of driving any headphones.

It seems to me like a lot of tubes for such an easy to drive pair of headphones, especially using a transformer.
As TG said, a single 6E5P is capable of driving a lot of headphones, given the proper transformer. A variant of his suggestions is to go parafeed, as I did with this one, as there are more available transformers for headphones made for it.
