houstonreef, while I do not have the JC1, I did own the A21 and also had issues with the humm/buzzz. I found that the amp was very sensitive to how well the interconnect was seated. Only a slight mis-seat would cause a buzzz. Try wiggling the interconnect around and make sure it is pushed all the way in. I hope this helps.
