hmm.
how can i reduce the current?
just replace the 47ohm in the source of irfp9240 with higher value?
or there is something more?
because my preamp seems not need current that high.
sorry about my bad english.

Hi Salas! the new supply
I run pre a lot of time. It is very good!
but still noisy at high frequency!
Entertainment very good bass sound!
high sound solution Í quite intense, not soft as before
What can I do??
thank!

More than references from alexberg and you about that JFET solution to work too, we don't know about its tone etc yet. You talk a whole preamp unknown to us. If your voltages are OK in your shunts and it does not have a problem, we have to wait for more evaluations from other members so to know if its tone is better or not and where. As for hiss or hum, we have never had references for such attributed to the supply part.

Ok! It is word many times, I run from in evening to tonight I word well.

R6 C3 in bottom schematic are way off spec. 3R3 1uF is correct. R6 on top schematic must be 3R3 again.
*R6 C3 are termination Zobel. Don't change the values, its bad practice.

quanghao, nice of you to share the drawings. Thanks!
There are two R6 on bottom schematic (R11 became R6). The title needs a bit of fixing.

The base stoppers 47R named again R6 are OK in value, I meant the ones to the right across Vout. Yes, the schematics better be done again with correct Zobel values and no double naming of parts. I see that 30uF+30uF in the bottom schematic for CRC in MKP, proved enough. That is good.
My Chinese won't be much better! (and most probably my English too!) 😉
Nonetheless I (we, I suppose) appreciate Quanghao enthusiasm and effort!
