I had some extra time so I removed and deconstructed my my clock yesterday and it's been keeping good time for the past 24 hours. I'm thrilled. The instructions on the 911 bulletin board are perfect and the fix is to replace some old capacitors. The capacitors are less than $2 each. The stock specs are 100 microfarad 16v, but I had easy access to 100uf 50v so that's what I used instead.
