[Milsurplus] Alignment Info BC-221-AK?

[Bob kb8tq]

Hi

I think that the simple answer is to re-zero it and move on. Back in the day, you 
probably sent it back for a new calibration book. I’d bet that most of the calibration
books are past their “use by” dates anyway.

I have replaced the trimmer, but I think someone has been inside the unit with an alignment tool, probably not realizing that the trimmer was shorted.  I can't find any info regarding recalibration after replacement of the components in the oscillator section of the unit.  I'm sure at one time, there was something out there designed for depot techs who had to overhaul the units.
