Thanks for all comments so far. 

As many have suggested, my test set-up was suspect due to a possible ground 
loop.  I repeated the test with a 3-prong to 2-prong adapter on the scope power 
plug to make its chassis floating.  Interestingly, the 60 Hz ripple was still 
present on the measured signal!  

To K9YC's point, I will try to locate a bad filter cap.  Thanks for the 
suggested method.  BTW, your Titan schematic is fantastic!  Everything on a 
single page makes tracing a signal path so much easier.

73 & HNY,
