The switching supplies sold as neon tube drivers CANNOT, in my experience,
be used as TC supplies, even with the addition of rectification, smoothing
etc. The supplies I have seen do not provide a CW HV output, rather they
output spikes of HV (6-10kV) 2-4 times a second to strike the tube, and then
a CW output of 600-1000V to keep the tube lit.  This means that after
rectification and smoothing you will get a 1-2kV output, which is pretty
marginal territory for any spark gap tesla coil.

The fact that you have to use a DC supply also means you either have to
accept a 50% power loss in a resistive HV side ballast, or use a charging
choke which will then make the supply as big and heavy, if not more so, as
an equivalent coil and core style neon supply.
