Nice of you to join us.

If this is the make I think it is (perhaps represented by a dealer in our
area, no?), I have once or twice found a buzz emitting from the metal
handles attached to the back posts. Try tightening the screws until you
think they will snap and see what happens.  This seems to occur most
frequently with the 108's and... well, I've had all the verticals do it.
Try it, it just might work.
