Re: topload questions

When you add a large topload you lower the res. freq. of the secondary
system, so you need to add considerably more capacitance or inductance in
the primary system.
With large topload increase you usually need to add more capacitance, and
this, of course, requires more power (mA) from your power transformer.
I'm attaching a paper that may give you some guidance.
