Anyone know anything about re magnetizing a C4A ringer?

Thanks for that ITT documentation Dennis, that was worth starting this thread even if there doesn't seem to be the "quick fix" that I was hoping for.

Does anyone know if the very late production C4A ringers (As seen below), which seem to have Ferrite magnets were given the same "tuning" procedures the earlier Alinco units were given?

Hi Dennis:

The ITT document listed in this thread is part of the larger ITT volume I read back when I wrote my observations after taking the ringer apart.

Sorry, but I have no error bars in my measurements to report. I did one set of measurements (one operator), only once because the flux went down after taking the ringer apart (just as stated in the ITT document) with only one ringer.

Thank you Jorge, for your input.
