| DC Offset Blocker/Killer - where to buy in the USA @ tomiiv30 As for DC on the AC mains. Nelson Pass If you are experiencing mechanical hum from your transformer, it is often caused by the presence of DC on the line.

| Too much of a good thing... Is the wire gauge of the cords you used at least 14awg?Just curious is the wall outlet a 20 amp dedicated circuit? What are you using for the wall duplex receptacle? | |
| Too much of a good thing... @ audiojan Did you use the stock OEM power cords, that came with the amps, when you plugged them directly into the wall outlet? | |

The 10 amp Line fuse is a lesser value than the 15 amp breaker. The actual FLA on the amp is more than likely 8 amps or ... | |
