I have found the diode actually hinders the process, if you have a diode you actually stop the circuit from resonating (at least at this stage, there maybe some need in the future to try the diode) as the circuit works by bouncing the charge through the inductor to make the field collapse increasing the voltage potential on the plate. As for the chokes the secondary on the transformer acts as my choke in this system, with the further developments there may be the need for a dedicated choke.
A video showing the start of resonance is not very interesting to watch. I use distilled water so that straight DC is actually quite slow (we are talking little to no production) thus when i used the circuit and got some production i was impressed enough to push on with the theory and go further.
Thanks for the Vid Alan, i have done that, blown the end out on SS tubes, done HV power supplies and lost a section of roof from my shed going down the Tesla idea. What happens is that the voltage potential is keep at max and arcs inside the HHO mix due to its low dielectric properties. HHO + Spark in a confined space is not good. This theory runs on the idea of once the voltage starts to break apart the water the voltage drops inline with production vs amps introduced to the system, also as your not forcing more amps onto the plate but letting the charge circulate through the circuit there is not the variables there to promote arcing.
