Original poster: "Richard Modistach" <hambone-at-dodo-dot-com.au> hi all, in the teslamap program the resonant tank cap for my transformer (15\30-240v\50hz) is shown as 6.8nf and the LTR cap is shown as 8.9nf. is it acceptable to use a cap value somewhere in between\including these two values or is it either\or with no in between? regards richard aus.
