Counterpoint SA 220

I recently purchased a Counterpoint SA 220. It's in very good condition and sounds great... just as I remember my SA 12 sounding.... BUT, I can't get rid of the hum. You think I should replace the tubes? Has anyone had in luck getting these to quiet down?

Sorry, no line conditioners here...

I have a dedicated circuit for my amp on the front wall between the speakers and another dedicated circuit for the components on the side wall.
