Well, Corby may have started something.
I had the pieces to a Frequency Electronics FE-5650A lying around in a
bag, so figured I would share as well.
There are two photos. The first is an exploded view with the lamp
(not dis-assembled) at the left. In the center is the microwave
cavity with the filter and resonance cell (heat shrunk together) and
the magnetic shield that goes over the whole assembly. At the right
is the cover that goes over the cavity with the C-field coil inside.
The second photo is the end view of the lamp assembly and the Rb cells
turned on end. They are miniature (about 1/2" diameter) compared to
the HP 5065A.
