HP-8569 Spectrum Analyzer Repairs

[AF6LJ]

My newest one came from someone on the ZED , and did not have all functions , then more quit after looking into it more .
I've read that if in storage sitting on the feet on back / front facing up , that some lube ? in the main oscillator flows over time and you can loose the signal , have you come across this ?
   

I have not heard of that, wow...

I'm guessing you mean the 8640B?  If so, yes, it's not good to store them on their front or back because the cavity lube flows.  I haven't seen it myself but I understand it can take months(!!!) to get back to normal.

Otherwise, a fine signal generator and you can have mine when you pry it from my cold dead hands! 

I feel the same way, as a matter of fact I would love to have two.

When I have time I will repair the thread...

It has been a long time, and I am well aware what a pain in the posterior repair of the thread would be, but I would like to plead with you to take the time for the sake of future restorations.

I had the pleasure of reading this thread before the photobucket fiasco and it was absolutely top notch.
