[time-nuts] Lamp for FRK Rubidium Needed

Just in case you weren't aware, bad lamps can often be
resurrected by the judicious application of heat.  The idea
is to heat the bulb enough to evaporate all of the Rb
that is deposited on the glass (making it black), and then
let the lamp cool.   The Rb will again condense out on the
glass, but this time it will condense out where the lamp
is coolest, and will spare the rest of the bulb, allowing
the light to get out.
