Thank you Peter.

And also I got right voltages in the end of PSU, +15/-15 and +48. So I dont know what is causing the hum then, is it ground looping? I have done all the ground cables in the right position.

Thank you

Those voltages are just fine.

I would have to have the unit in front of me to diagnose the hum.

Thank you Peter  :)

I did some modifications on my PSU and is based on your V6 PSU that you post recently on "Green mic pre Buzz and phantom power hum"

And Viola!! The hum is gone  ;D
But I'm not sure if that's the right thing to do haha

Thank you
