Yes, very nice pictures. That thing is really built and looks like it
should be easy to work on and experiment with.
I still have to say that I doubt the cavity is off-tune unless
something serious happened to it mechanically. Is it even adjustable?
If so, maybe someone previously tried to

If the Rb cell drifted enough (maybe if it was filled with water)
to de-tune the mechanical cavity resonator, it wouldn't work at all.
Only a small amount of the RF power in the cavity is coupled into the
Rb gas. The bandwidth of the Rb resonance is a fraction of a Hz (Q in
the millions),
I will strongly agree about the cavity and not tuning it. The key is the
multiplication chain and unless the srd is bad the rest of the chains
pretty reasonable in the frequencies used.
Typically a fair amount of power just before the srd.

Great pix with the right level of detail to actually see and analyze stuff.
Second what a find you have there. A real mans RB nothing small about the
gas cells.
Good also to see many what I consider to be common components of the late
60s and 70s. Also I noticed little or no
know.

Other thing I have no clue to. What happens to photocells after X years.
I suspect they degrade also. Since thats the frontend of the rcvr that
would do quite a number.
