Have you measured to see if your findings were correct?
So glad you guys decided to release this! Combined with the information in the download e-book and this thread, this is now a complete public release of a stage 1 type device. I hope everyone realizes how important this is, it can now be replicated around the world, at least by those skilled enough in electronics. I think it is likely to be unstoppable now.
Now that I have a working HV supply I will try it attached to the antenna later today! Hope to have more test results soon. I also invested in a true 100x HV oscilloscope probe with 5kv capability so I can do better measurements on live circuits.
Back when I sent this to soundiceuk originally, I was driving the primary with the PVM12 directly as you would a Tesla coil. Using a regular spark gap instead of the PPV will make the coil oscillate of course, but I found that once I changed the anode to the aluminum point that it worked much better, with less transient and much cleaner ringing.
