hi sue,
            iv tried both setups but on an induction heater as opposed to a
tesla coil but the same applies. i would think that the main advantage is
with the series resonant is you get natural voltage rise which is proven to
improve performance over current rise (oltc) also in parallel res mode you
need major caps to handle the current
cheers
