@Grum,

So if i get it correctly, your core in a royer setup, will peak 200v p-p with bipolar transistors (TIP3055) but when replaced by FETs or added diodes in parallel with them, then the normal x4 p-p applies. Correct?
In other words, if you put a diode in series with the FET, then you should observe again 200v p-p if not more. Hm.. i do not have a clue about this and i will reftrain from theorizing. Soon i would grab a royer in my hands and i let know everyone.

ps: A large inductance -as large as possible- that does not saturate under any nominal load current is an efficiency must-have. I have run royers with no series inductance at all, but with seriously impaired efficiency.

I am going to try and find the Acoustic resonance of the Ferrite using a Ceramic pickup from an old record player. 

Just remember that the core can vibrate acoustically transversely or longitudinally so direction of the pickup matters.
Also, when acoustic standing waves are formed in the core, there will be some places on it where vibrations cannot be felt at all (the nodes) so you gotta move the pickup around to get the feel of nodes and antinodes.  On open flat surfaces you can use sand for this. See here.

   I think that what I am seeing is not the "nomal" results. Why? Because there is NO shocks, and there is no ringing, at least not yet. I'll continue with my tests today. 
  I was able to dimly light a 50 watt 120v incandescent with a wall adapter 12v, 500mA.
But, was not able to light it with my small solar panel, which my only put out about  200ma. Just playing around with it...

Hi guyz ,

Yes as you can see Fet's are the ones for this work. they work differently for this circuit.
and yes only poly caps, MKP and mylar must be used here.

@Nickz:
Nicee you managed to make it work and able to experience how it functions. Yes that I have tried to, put a ground wire on the Surface of the heatsinks also, enhances performance. I accidentally laid my hand on one of the sinks and was barefoot when i discovered It needed ground there  . crazy. haha.
By the way you should try to connect more light bulbs afterwards because the more you connect, then you will start to hear the singing of the core.

@ Grum:
Success with the testings . Hope to see the progress too. Those 2000V rated Polypropylene caps should do alott of charge  , I wish I could get my hands on those, as for here I cannot get them. I have to buy some from Ebay or so soon.

@ Verspies:
Thnx for sharing  the link of the Java Simulation of the circuit with modifications . 
That would be a brilliant idea to using sand or some other to see the vibrations of the core. Would make Geometric Designs  and able to see where the sweet spots are, as you said the nodes.


I will post a vid or two today guyz but sadly not with good measurements yet aight, but will show what it does with the meter I have now trying methods out. 

Cheerz ~

Dear baroutologos.


I have attached a sketch of my present setup for clarity. I hope it is not too rough!! 

Cheers Grum.

Oh and as a PS. With certain capacitor values and lower frequencies my mid range DVM actually confirms the "near RMS" value!!
