Default questions about transformer and ajx

I've built dual-mono Aleph5 with 2 transformers 400W(25V-0*2) several years.
The rail voltage is about +-30V now.
I'm considering next project to A30 or Aleph j-x.
The A30's voltage is about +-25V.
Could I use CRC filter to lower the voltage to +-25V ?
Is this a good idea ? ( new transformer is very expensive ....)

Then the Aleph j-x...
Is this CRC filter(+-25V) suitable for Aleph j-x project ?
What's the Aleph j-x power consume when running in +-25v ?

Your power consumption will be your rail voltage x your individual fet bias current x the total number of fets used.

Attachment is simulate with PSUDesigner a CRC filter to reduce voltage to 25~26V.
Do you recommend this ? will this degrade the sound ?
Is 25W 3ohm R enough in this circuit ?
