Transformer is making a noise - how to cure? | diyAudio

The amps are Soundstream monoblocks. I suspect the noise is due to one of two problems: 1. There is a significant amount of DC in the AC power supply hence why it is humming. 2. The windings on the transformer may not be as fixed as it should be so it is causing minor movements that induces the hum.

Audio Noise from my step up/down transformer

The hum from the transformer is mechanical and not necessarily translated directly to the quality of the AC to the amp. That mechanical hum could be a symptom of saturation caused by overloading or DC offset but some just do that in some places. In other words: Don't shoot the translator. At least, not before questioning the usual suspects.

Audio1Man said: From what you describe is it Mechanical Hum? This can be caused by several things. 1. Disconnect all secondary windings. Power it ON. 2. Is it still humming? If so you need to find out if the core is in saturation or just the windings are loose. By measuring the excitation currents (TX not connected to any other circuits).
