Orphean and BD30 (Orphean)

Hi Bert,

I have built a stand for my Oprhean horns in which I have built in the BD30 amps. Now there is a little hum which is induced by the transformer of the BD30. It can be heard when the orpheans are completly disconnected so there is no electrical connection to the BD30. While this shows some of the extraodinary sensitivity of this system, its still annyoing. Is there anything that can be done to prevent this or do I have to place the BD30 somewhere else? Maybe a metal housing for the amp would help (shield)?
