[time-nuts] Thunderbolt E failing

[Kevin Schuchmann]

Newbie here looking for comments from people with more experience with 
thunderbolt E's to comment on what I am seeing.
Unit is jumping and ramping the DAC one direction then goes stable for a 
bit only to start jumping and ramping the other way.
Oscillator heading south or more likely the electronics package?

Was running OK, shutdown and put away for months and then restarted and 
has been running like this for months and not settling down.

Thanks
Kevin
