[time-nuts] Symmetricom X72

[Germán Herrera]

Hi everyone

This is my first post on the list, tought I've been subscribed for some 
time.
I'm in the process of troubleshooting an X72 which recently started to 
be unable to acquire lock. I've searched online for pics of this 
standard and wasn't unable to find anything, so i took some nice 
pictures which I'd like to share with you:

After disassembling it I found that an optical filter which is supposed 
to be glued to the light path of the lamp was loose inside the unit. I 
attached it again but the issue persisted.

If anyone is able any information about the thing (such as lamp working 
temperature, resonator temperature, lamp excitation frequency, etc..) 
I'd be grateful. It's sad that Symmetricom's manual is not able to 
provide any useful details.

Cheers!
