145 wimped out

[cochrans@apple.com (Stewart)]

Had an outdoor gig last night.  I set up my 145 only about 6 feet away from
me. At first I thought it wasn't playing at all. I leaned a little closer
and could hear it, but only just barely.  I turned the M3 and the Preamp up
all the way and this, of course, distorted the signal, but it's the only
way I could hear anything.  When they mic'd it, they had to turn the gain
up so much that the wind generated by the horn and rotor was almost as loud
as the signal itself. At this point, my monitor, which was about 15 feet
away started feeding back because the mics were so hot.  I finally just
gave up and used the Pro-3 by itself. Since it worked fine, I concluded
that the problem wasn't in the Hammond or the preamp.

So what's happened to my Leslie amp? Everything sounds normal, it's just
that the volume has been reduced by more than half.  Is there anything
obvious I should try first?

Thanks,
