I've been having a lot of fun with this time-nut stuff over the past year or
so, and I'm thinking about going atomic in the next year (GPSDRbO), but I'm
a microprocessor kind of guy, and I have incredibly clumsy hands with
electronics and soldering. As much, I'm wondering:

Been there, done that. This unit had multiple problems with bad
soldered ground connections. I went through the unit and resoldered
everything that looked the least bit odd.

Dickson,
I have a paper set of manuals. My recollection is that it is a multi-part
set.
What, in particular, are you looking for?

You can download PDFs of the HP 5372A TI Analyzer from Didier's site at
http://www.ko4bb.com/manuals.
Just search for 5372A.

There is a Op manual along with other info on my Web site

I actually think thats what time-nuts is about.
I know I have done things with RBs and a CS that I never would have thought
I would or could do.
Heck its broke and junk and it feels great when you get the thing working
again.
Whats amazing is that when these were designed they were so cutting edge

Joe,
Thanks for your thoughts and ideas. I expected that this would be an
interesting project and it hasn't disappointed me. I'm currently
reading an article from the Bell System Technical Journal on microwave
cavities so the learning continues. Hopefully, it will never end.

Ed,
Sounds like you are on the right track.
These things are fairly simple and fun to play with.
The Rb assembly on the 5065A can be opened at either end. One end has the
Rb lamp and is mounted by 3 screws, against the 'end' of the 'cavity'.
Inside that is a 'filter' assembly and beyond that, a
Great thought on using the led. That goes in the bagOtricks.
