sorry rob..jumping between laptop and poking at the bulldog to see if its magically fixed itself and didn't see reply...! there's no sound at all mate, silence...have wriggled wires around (usually my 1st action when tank's having probs...!) but nowt..all connections with speaker seem ok and board but dunno...? getting late and i'm not too clever with the electrical side o things at the best of times...!!

planning on replacing speaker at some point but want to know what the problem is 1st..? (and my sonwill be out here in the garage every 5 minutes tomorrow to see whether i've fixed it..!!)
cheers, rgds stuart
