Was the "savage" deliberate or did you mean "salvage" - they are probably both accurate.:)

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.
