Brendan;
Take a few minutes and give us the complete details of the
secondary coil you want to work with. I mean all relevant
construction details: physical coil size, coil form material,
wire type and size, number of turns, coil shape.
With the proper data any number of us can be of assistance.
You could do the basic math yourself with a Tesla formulary,
but there is a lot of practical considerations concerning things
like the inductance per unit volume, breakdown strength, wire
resistance, etc.. Coils designed for solid state operation
frequently differ greatly from coils built for spark excited tank
circuits. Spark excited tank circuits require a heavier coil,
with less inductance per unit volume, than is typical in a design
for solid state operation.
