Hi All

Thanks for point out my fundamental error. Thinking in terms of the simple
setting of caps C1 and C2 in series across a DC source with total voltage V,
then V1 = C2V/(C1 + C2) and V2 = C1V/(C1 + C2). With C1 = 2uF, C2 = 0.1uF,
and V = 63,000 volt, we have
V1 = 3000 volt and V2 = 60,000 volt. So the Geek cap will see most of the
potential difference, far in excess of its DC rating. The moral of this
story is, "do some math. before you talk."
