FWIW, I've noticed these clicks from within my KPA500 too. I always assumed they were thermal expansion and contraction of hardware within the amp. I ignore them because they have never been associated with any problem with the function of the amp. Besides, I don't know how you'd begin to try to isolate exactly which bit of metal in there is doing the clicking to be able to do anything about it.
