Hi I have had beomaster 8000 for a long time and its fully restored two years ago,  its used only for radio, but today I was connecting to TP1 rca cables to connect my phone to it. I notes that when phone is not connected there is considerable noise from TP1, it disappears dough when phone is attached and music is played. the same time I tried PH and there is allso a strong noise (not hum) present. Week ago the beomaster was fine without.any fault. Radio sounds super great and much louder then TP1 input.

What is wrong it?

The noise disappears when you remove this RCA cable? When you plug in the phone the noise disappears?

This is completely normal. RCA to Jack cables can somehow act like an antenna and pick up noise.

PH noise came from input trimmers on preamp. Cleaning them got rid of the noise.
