Nice work. I used the same "eco case" from Hifi2000. They do the job for a fair price )
Any measurements to check how noiseless could be those linear PSUs ?
PS : you should add a DC+EMI filter between AC mains and transformer this is important for linear PSUs
With balanced line preamp works great, now with unbalanced to balanced adapter and unbalanced preamp is a little noisy , idk why

Very,very minor but if your "clemas" are made of steel you may want to change them to something non-ferromagnetic.
Nice,clean work otherwise!
