[time-nuts] Rubidium freq standard - temperature

I was able to get all 5 of these EG&G Rubidium Frequency Standards running by replacing the caps as another member found.  They have a large heatsink on them, no fins, and are running at 43C.  Is that too hot?  Should I bolt them down to a larger heatsink?  They consume a little over 9w after they lock, about double that while warming up.

The only other issue I see is that the 8bit frequency setting doesn’t allow me to set the frequency closer than 5E-11.  I don’t know if this is good for these units and RFS in general or not.
