Sony TA-F707ES Netzteilbrummen

Hi,

If the sound is comming out through the chassis your Power-Transformer may be the source of this annoying humming sound.
If it doesn't bother you, it most likely won't bother the amplifier.
If it bothers you, the transformer should be replaced, but it's expensive. Some times the transformer mounting screws can be loosened, the transformer turned a bit and the screws re-tightened. The slight difference may be enough to stop the transformer-humm.

My advice: Forget about it.

If the humm comes out through the speakers, it's quite another matter and the amp. should be repaired immediately.

Kind regards,
