[time-nuts] Cesium standard prices

[Brooke Clarke]

Hi Perrier:

The problem is that the Cs beam tube is similar to a filament light 
bulb, i.e. it has a limited life.  Most of the used Cs standards that 
are on the market have worn out tubes.  The 5060 is a very crude first 
generation standard see:

for more modern Cs standards see:

PS I found the FTS 4060 as a new old stock item.

The Thunderbolt GPS Disciplined Oscillator offers very good value for 
the dollar.
