Certainly I deny it. I was merely trying to get clarification from you. 'u' could have referred either to 'micro', or to the core permeability coefficient. And, like Ronsimpson in post #5, I was unsure whether you were trying to build or just simulate a transformer.
Ya, I should have communicated it better, luckily, Chris understood me he's been helping me out a lot. I do want to build this, but the first one I built from the instructables website didn't work. Chris suggested trying a center tap on my transformer, thats when I thought maybe I really should first try to simulate it.
I already rapped another Transformer, but stopped doing anything until I can get a handle on this thing.
Have a look, the original Schematic and Claim
https://www.instructables.com/id/A-reliable-plasma-speaker/
I believed in the beginning that this circuit would be ok to build for a guy like me. Trusting the Instructables website. I spent all 8 day's of my time off working on one "dam" board, only to find that it wouldn't work the way Author Claims. I would like to challenge that claim, I have followed intelligent engineers working on Developmental Projects as a Tech and held a position as a QC and QA agent, with the Largest Shooting Range Company in the World. I'm not a complete idiot, but I don't want to be made a fool or allow others to suffer this expense.
But, the truth maybe that it's all to generate hits for both sites and I was duped. I then found a few people, including a Member on AAC who tried to build it, and because of time, he couldn't continue or he would have found fault with it, and maybe mention it to Instructables.
I'm willing to continue until it's proven to be a faulty circuit or not. If it's Faulty, I want instructables to pull it from their site and make the Author stand up for his claim.
Thank you for leading me to LT Spice. Maybe I should sim the first schematic he posted too!
I just want to stop the Madness, either he's a Genus or a Fraud.
