Yes I will do, they have been very helpful in the past. Its often good to
get input from the other side of the pond as well, and Usenet almost
always
gets you more information than you were looking for or thought you needed.
This guy has actually brought one of the amps in now, its permanently in
protect, probably an output stage. Delving further it seems that he has a
variety of protect problems, not just the startup one I originally cited,
some will protect once a signal is outputted. He's been swapping his amps
around with his touring rig and an install, sometimes the amps go into
protect during a gig then mysteriously get working again.
Could be speaker cables / crossovers etc, but I wanted to find out if
these
amps have any history of going into protect for no apparent reason.
Cheers,
Gareth.
