Re: Needed: SSTC History and Achievements
Original poster: "Eastern Voltage Research Corporation" <dhmccauley-at-easternvoltageresearch-dot-com>
Thanks for the great info Terry. I have spoken with Steve Conner a bit and
he has filled me in with a lot of the
OLTC stuff, but your file will be of great help also.
Once i compile this list, i'll post again here on the list and see if i can
get a good percentage of agreement among the
other coilers. There will always be some disagreement, but as long as i get
a somewhat accurate representation of
