Linear power supply

[readbueno]

Any suggestion for low-noise power supplies which are for sale here in Europe (and which are affordable)?

Maybe apply a suitable, simple low pass LC filter?

That is all the inline filter above that effectively kills the noise from the supply. Still have the "spare" PCB if anyone would like it. Takes a couple of torids from Amazon/eBay with provision for two capacitors on the in and out side.

Could you show us a picture of it and where it fits, i.e. will it fit inside the case for Blue somewhere, or is it a separate "box?" Simple Circuit Diagram?
Or is it on the output of a PSU, Would it fit in the box with a small linear PSU. I am waiting for components to build a small linear PSU hopefully it won't
have too much noise at the frequencies of interest.
