SB-102 - more troubles

[Guy Giacopuzzi]

Is a "recalibration" ever really necessary on the 102's LMO?  Or does a 
relube solve the majority of the troubles?  I guess I'm really asking, 
how can a device like the LMO actually /get out of calibration/?  Are 
there any components in it that can drift in value?  I understand the 
problems with the grease and  contacts changing value, but can anything 
else in the unit "drift" over the years?

However, it has been my experience that the company that manufactured the solid-state LMOs did not perform the close calibration that TRW did on the tube-type.  In every SB-102 that I have worked on the LMOs were pretty much "spot on" at the 100 kHz points.  But, in between I have seen them as much as 5 kHz off from the dial reading.

From what I have heard this is basically a "labor of love" because what he charges is very small when considering all the work that is required.  Unfortunately, his name and call escape me right now!
