Primare Knob Posted August 10, 2018 Share Posted August 10, 2018 I have a Parasound A23 that has started to hum, and can be heard through the speaker. The amp has one transformer, two speakers connected, can be heard when only the amp is turned on and all other equipment is turned off/ not in stand by, and can only be heard by the amp or through 1 of the 2 connected speakers. Any clue about what is going on? I do think that it is not a ground loop, and I would think that if it is a bad transformer it would be heard on both speakers. I am no expert so I hope to find some good ideas here. Link to comment Share on other sites More sharing options...
Hydrology Posted August 10, 2018 Share Posted August 10, 2018 Disconnect everything from the amp except the speakers to eliminate anything else. Link to comment Share on other sites More sharing options...
