Well, let's see... it made a big CLUNK when the contactors kicked in,
then the high pitched whine of the exciter/driver fans could be heard,
followed by the sound of the blower in the PA coming up to speed.

Like I said, it made a lot of noise. But I never heard it make a big
bang, if that's what you're wondering :-)
