integrated amplifier with aleph p1.7 and mini aleph

[vivanco]

new update:
I moved out of the chassis the toroidal transformer dedicated at section of the power amplifiers and as if by magic the buzz has become almost zero, that is audible only with the pot set to maximum range and however very much attenuated;
now I ask you some advice on how to run a screen, so you can return the transformer inside the chassis, consider that there are already inside the chassis partitions of galvanized iron with a thickness of 1mm, creating separate rooms, where, in one of these rooms I placed the two transformers, but this has not proved sufficient, give me a hand.
