I have a couple of 300VA toroids in an audio power amp which generate a fair bit of mechanical hum. Since their rating is very conservative and they don't run too hot, I thought potting them might fix the hum. Can anyone suggest a readily available, easy to use potting compound? I've tried the obvious things like mounting them on foam of different types and surrounding them with sound deadening, but 50-100 Hz is pretty long wave-length to try killing that way... Thanks, Graham B
