Ed, you seem to have it backwards! You want to get AS MUCH INDUCTANCE
AS YOU CAN in any given secondary! Remember, for a two coil system;
Vsecondary = Vprimary * SQRT ( Isecondary / Iprimary )
As far as the appropriateness of the stranded wire, that is dependent on how
thick the insulation is, if it is relatively thin then OK, BUT if it is
thick then the secondary inductance will be too low and the output will be
radically reduced.
