[time-nuts] 5065A Rb Cavity RX - Varactor repair?

[Ulf Kylenfall]

Strolled into my little lab only to find the 5065A's Red Integrator Limit  
light on. Control negative fsd. PhotoCurrent OK. No 2nd harmonic. 

Was just about to power off and start to disassemble the unit. 
All of a sudden, the Integrator light went out. Control went to zero 
and by pressing Reset, the unit locked with previous 2nd harmonic 
level indication. 

What ever the problem was, I do not know. I guess I can fix (redesign) 
the synthesizer and replace some semiconductors that have failed 
but if the problem is in the Rb Cavity RX unit - Varactor - there is a 
problem. From a similar unit (but without the TED) I can see that 
some part of the varactor assembly can be dismantled, but then 
there are a few tiny screws that seems hard to reach. 

Has anybody repaired the Rx part with the varactor assembly?
