If you have hum on one channel, often time it is because one of your components is placed close to some electric field such as a transformer or power line. Try to move them around one component at a time to see if the hum changes. I had the same problem when I place a DVD player under my preamp. Once I move it to a different shalf, the hum went away.
Monoblock disadvantage or...?
My friend has QuickSilver M60 tube monos(2 x 12au7 input and 4 x EL34 out tubes).
When I bring my ear to each of the speakers one speaker has bigger hum of 60Hz than the other.
The hum though isn't audiable from the listenable distance.
I've hooked them up with different sets of interconnects but the hum difference was still present.
What I might want to check and how?
