loud ac hum-what can I do?

I have this older Grommes solid state pa amp that hums from both channels. At fairly loud listening levels the hum does not intrude. This amp sounds as good as any amp I've had with really good bass control and good tone except for the ac hum.I suspect it is the power supply. Can filters be added or what can be done to cure this?
