On a hunch I opened the front panel and reset the blinking amber battery alarm lamp, and voila, that noise went away. Makes sense when you think of the power variations associated with a blinking incandescent lamp.
There was a Tektronix sampler that had a few ps sampling jitter to the tune
of a blinking LED on the mainframe :-)
