Obviously, the old boys are on the right.
Jim, was I too early in pulling them?

Including my neighbor, something of a tube sage, who noticed them and said, "You didn't fall for that crap, did ya?"

If it IS sporadic (not to be confused with intermittent) I'd also consider external interference as the culprit. Try rearranging (or even switching, not to be confused with cycling) speaker cables and interconnects and see if that helps. I'd also hunt for other appliances that could be cycling (not to be confused with switching) at the same time the noise appears.
As an aside, my computer was driving me nuts, making these bizarro noises that sounded like a clogged fan bearing. Took the cover off twice to spray air, but no improvement. I'd resigned myself to replacing the fans, and went to get a cuppa coffee to steel myself for the effort. Walking back, I noticed the indicator light on a Riddex pest repeller flashing in time to the noise. Unplugged that ... problem solved.
Speaking of driving me nuts ...
