I call a technician who said he could fix it... and he did it.
He change the L501 component on P500 board. Thanks god i have spare parts from other marantz.... technician did many other "magic" tricks on FM, but changing L501 the volumen on FM was increased to normal listeninig levels.......

Not familiar with the 2440, would suggest starting a new thread for this issue.
