Everyone I want to thank you for your help.
I was sent the snippet I needed and the 207 lives. Copying wwvb right now.
Needs a bit more tlc like getting the phase accumulator working correctly.

I finally built a timelapse movie of the 60 Hz clock + webcam
experiment. It covers about a week, but there may be a gap or
three. It's a 20 MB file (tested with VLC and mplayer).

Mode B is the same crystal on a different frequency
(about 10.95 MHz). It does not have a turnover and

Does your Mode B 10811 use a different xtral or same xtral, different
frequency?
What does Mode B do better, ... and worse?
Why was it not used in the 10811?
When trouble shooting a freq stability problem, usually the more data the
better.
What can really help to narrow down the cause or see

Fellow time-nuts,
I now have three 5065A in my lab (not all mine) and I can now conclude
that the A15 PSU board C8, C9 and C10 caps has gone bad on all three.
The only difference on the first one is that the process has not gone as
far as to blown the caps, but two of the leads has began the p
