Does not have a sound of its own, you only hear the EL84:

Nonsense. The T-Reg or a simple Maida regulator will sound great when implemented correctly.
You’ll find an excellent PSU in my post which will provide 560V / 400mA and can be easy enough modified for your needs, since I attached LTSpice models. PCB Gerbers included as well. The design is by BugAmps and I can ensure you, if you are careful about grounding, you’ll get a dead silent PSU.

I cannot imagine why anyone would want to use a regulated solid-state power supply with tube power components. The beauty of tube sound is at least partially due to the sag of an unregulated tube supply.
Some just want to listen to the music, as unmutilated as possible.
Others use their amps as musical instruments or effect boxes.
It's all about personal preference.

@tubekiddo, I looked at the design you linked to. Nice overall setup, very complete.
I noticed tho that the HV psu is not a regulated design, it's a source follower (fancy name cap multiplier), right?
That will sag under load.

It is rarely mentioned but others use their speakers as musical instruments or effect boxes. 100% agree with you, it is personal preference.
It has a smooth ramp up, stabilizes at ‚normal‘ load and will sag if you try to blow your boxes…
Maybe for a guitar amp in push-pull. For an SE amp quiet is the main concern. A class A SE amplifier doesn't have any appreciable sag unless you do something really weird or wrong.
It doesn't sag that much, but it produces a signal related ripple at B+ due to the source follower Zout.
That ripple, which is a distorted version of the signal, is directly in series with the output signal.
There is a reason why most SE amps sound different from each other.

You don't need any regulator, just good rectifiers and filtering capacitors.Don't believe everything just because it sounds sophysticated! Tubes like el84 were ment to deliver very high quality sound with no regulation.
True.
SE Tube amps are not exactly the pinnacle of Sound.
Haven´t been since ... when? .... 1930?
SE (tube) amps are objectively not very good in reproducing sound without adding stuff and taking stuff away from it.
But that doesn't mean people can enjoy their sound, personal/subjective preference.
There's nothing wrong with an amp that acts more like a musical instrument than a precision reproducer.
Talk to a guitar player!
