Default humming sound from receiver

Most likely the main filter capacitors, and the decoupler capacigtors
probably have to be changed in the power supply section. It is also
possible that there are other components and capacitors in the set that
have to be changed because of their age. This is common in these sets.

If you are not experienced in servicing electronic equipment, you
should give the reciever out for proper service. There are also serious
safety issues with servicing electronic equipment.
