The PSU for my preamp before the final wiring: No discernible noise or RF...
This is after making a few linear powered versions and having hum.

Impressive!!
I would like to supply a SE tube amp at 430Vdc 350mA per channel, and the deiver at 235Vdc 10mA per channel plus a variable 380-410Vdc 50mA per channel. The latter could be derivednfrom the former through a pair of buffered LR8.
Can the first 12Vdc be elevated by 80V?
I could supply the heaters of the 12at7 in parallel with two KT88 in parallel directly from it.

350mA is the peak value, but not being sure about the reliability of these SMPS at full power, I preferred to communicate peak value.
