I recently ordered a Vintage 30 from Mesa. I hooked it up to test it. It is giving off a strange buzzing sound when I run a 60Hz tone through it. Im pretty sure this isn't normal. It almost sounds like a loose dust cap, or a lead hitting the cone, but the dust cap seems fine and the leads don't look to be touching. What do you think?

Hi Kevin,

I sent you an email as well. The result you got is exactly what would be expected with a 60Hz signal being used. That is far too low a frequency, and a signal generator would not have the strength to drive the speaker. Thanks
