I'll do a post on resonant charging then, later.
Perhaps for your Grandpa's oscillator it could save a lot of iron if you start out with a high frequency transformer such as is often used with halogen lighting. What they do is, the first create an AC of about 40 KHz and then they use a small step-down transformer to get 12V. This 40 KHz AC will make resonant charging a lot easier (read: less iron required, compact design)

oh my gosh:

How surpassingly simple! :s I love the doing away with the 12v monster DC supply. Now this is what I am talking about!
Makes resonant charging easier? Im ready for the next installment! :)

You found LoneOceans! Look at his QCW... I tried to contact him, but he does not respond :(
But... erhm... yeah, a flyback circuit is very easy, as is a Slayer Exciter Coil (SEC). Look it up if you are looking for a simple HV source.

Yea I built my fair share of those sec designs.. but when compared to a 12v 40khz source off of a 120vac supply cuts down on alot of junk to package.
But im also having a desire to stick to the original desktop ideas that were perfected at maximizing the action at the terminals. This probably also includes the need for a good spark-gap for the quickest transients to reproduce the illuminating parallel wire experiments (transistors may not be as quick for efficiency sake).
The hallogen transformer + a flyback circuit sounds like it can compact the Blast part of this design. Leaving the spark-gap up for exploration still.
I remember your QCW plasma forming 'swords' topic... I also would like to hear another installment on that again :p

I included a sketch of the considered options. It seems that if the driving frequency is closer to the required primary frequency (in the case of a 40kHz Halogen ballast) the pan-flute addition would be unnecessary.
And then I guess it doesn't matter how fast the discharge is if resonant circuits are tuned properly. The critical property of the discharge is to not be so slow as to conduct in the wrong direction.
Interestingly enough I just found out that those 12v halogen ballasts have a halfwave envelope. Not exactly CW.
