This confirms a separate set of filter caps for each side. The thing here,
is that someone would have to know the specific model design, or have it
opened on their service bench in order to even start making assumptions of
what the fault may be.

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.

As far as I recall, the power supply on these is common to all channels,
thus if the hum is on one channel only, it is highly unlikely that it is
being caused by the main smoothing caps. The first thing to establish is
if
the hum is affected by the setting of the volume control. If it is, then
the
problem will likely be a front-end grounding issue. Any power supply
problem
will normally not have the symptoms it's causing, affected by the volume
setting, and will affect all channels equally.

many high end audio amps have their own bridges and caps per channel,
they may use the same xformer how ever.
