Malcolm,

Even for a multi-layer winding, 833hz is still unbelievably low.  I
could see maybe getting down to 8.33khz... if you had a ferrite core.
I've wound a few HF HV transformers (ferrite based) and most of them
end up in the 50-100khz range for resonance, and thats with the core
making the inductance magnitudes larger.  But i rest my case, there is
no need to convince you of anything here ;-).
