[time-nuts] Ultra High Stability Time Base Options for 53132A

[Bob Camp]

Hi

All of the MV-89’s that I have seen are very much a crap shoot in terms of 
what you get. Out of a dozen or so I’ve bought from various sources, none has
met the original specs on the unit. There have been a wide range of issues. Doing
a full test on one involves a lot of work. The problems with some of them are major
the problems with others are fairly hard to spot. 

I do not believe that’s a reflection on the original design of the part. I’d bet that nearly 
100% of them meet spec when new. I think it’s purely due to the amount of violence done to 
them when they are pulled from boards during the savage process.
