Neither the amp or the sub have grounded power cords.
I have discovered the ML Dynamo takes about 30 minutes to switch to standby in auto mode.
With speaker level inputs connected to the Onkyo A807 amp, both units powered from the same wall outlet, Dynamo sub on Auto, the sub hums for about half an hour after the Onkyo is switched off, then the sub goes quiet. Not so good.
I connected a bonding wire between the two units on 3_7_09. If I smoked some old audio gear I could just look at that as an opportunity, right?
Works fine. Now I have the ML powered from the wall and working normally.

Did you get the sub fixed? I know someone with the same problem - won't turn on, fuse is fine. May be due to different underlying problem, but wondered if you discovered what it was and if you got it fixed.
