Mr. Miles,
PCB for my layout, received from professional PCB supplier. Home etching is always a quick alternative😀....

Mr. Miles, making a layout for new fx100 psu... meanwhile i will try with another PSU that i have for the amplifier.
what needs to change on the Fx 100 PSU+protect for 70V rails? attached for reference.🙂

Here is the "quick and dirty" draft layout for New FX100 PSU as per the quoted schematic. It is compatible with schematic and with 18 mils min spacing.
Mr. Miles, can you confirm the schematic again, because I had significantly depart from old layout (more jumpers). Also kindly check relay connections.

I will keep improving it for reducing the jumpers and improving "symmetry"😀.

Mr. Miles, there was an error in FX100 PSU schematic shared . R9 (220k) does not connect to R15 (100k) in the layout shared by you two posts ago. Instead R15 (100k) connects to the junction of R18 and C13. I have it incorporated the changes in my eagle schematic . The schematic now corresponds to the layout shared by you.
attached are the schematic and layout. pl tell, if my layout is now ok, want to make PCB for it too.

Hi Juan,
I will correct the layout first as per the schematic and then post "eagle files " here. Dont have sprint!.

Hi Juan,
as said, pl find the eagle files attached. I am sure you will make much better layout in sprint!

Mr. Miles,
how does the layout look now? ready for etching?
