Help with cap value in bootstraped cf topology

I need help calculating “C” in this bootstrapped-cf 6dj8 topology.

My guess is 10uF would give a suitable 1,5Hz high-pass, but I’m need someones confirmation of that value.
I do realize that it need to be rated +200V, hence a electrolytic will provably be called for.
