[time-nuts] PRS-1- Rubidium

Jurg,

I did not see your picture before responding earlier.  Check the dipped tantalum on the right for a hole that spouted acid.  The device on pillars is a preliminary heating resistor for the rubidium bulb.  Be sure to measure its spacing from the bulb, if you are going to remove the circuit board, as this is critical to the warm up cycle.
