I have built one of those fabio driver boards ,every thing is ok but it sounds very hissey ,what would cause this effect , is it the transformer ,caps or my smoothing stage i dont know myself.I have changed the cap on the psu but that makes no difference.
Also i can hear a silt hum from the out as well is this too much volage or current ?
needs some help on this
