  How does DC get on the AC line and how would you know if it is there? What testing can be done?

    Follow the link that I provided further down on this thread for info on DC infiltration onto AC lines. It's a lot more common than most folks think.
    
    Also, most quality DVM's would be able to measure DC on the AC line.

  What would be a good solution if that's the problem or should I even consider it a problem? If that's just the way its going to be, I can live with it. If there is a simple solution, that would be better.

      The DIY DC blocker is more of what I was looking for.....a cheap fix. The transformer hum is an annoyance, not something that I was wanting to spend a load of money to make it go away. I appreciate you passing on the information. Thanks!
