Andrew- My original question regarding excess heat was in response to Terry Farrell"s comment: >I own a Boston GP-178, which is located in my home. I have about five rods >on it totaling about 190 Watts. I wondered if, at some point, the elevated temperature itself (even with sufficient humidity) can have some negative effect on the soundboard. It seems there has to be SOME limit, yes? no?
