[R-390] Role of the 3TF7 in PTO frequency changes

[sigmapert]

I was an active member of this list for several years in the
mid-nineties. After my retirement I'm back.

In context with building a jig for the measurement and alignment of
PTOs I began to experiment with the 3TF7. I measured the effect of 
power line voltage variations on PTO frequency. The results are in
accordance with the findings of Dallas Lankford.

I can document that the current regulator 3TF7 is the main cause for
the observed PTO frequency changes.
