I would not put a cap at the base of the transistor (i.e.10nF), but stick to one timing capacitor only (i.e. the 100nF). If you want more than one timing element, they must match, so they don't "fight" each other.
In fact you have the "spatial" resonance of your transformer coils also, so there is something to consider.
The point of my suggested changes was to make it self oscillate, the two pots just adjust DC and AC bias of the transistor.
I look forward to see your circuit.

Thanks Eric, can you post me a diagram, as I cannot picture this, the older you get the less the grey matter Thanks

This circuit has apparently been circulating for some time, Dr.Stiffler calls it ECAT.
"The polyphasing transformer is of a Theta core design and is made from a material that saturates at a desired saturation point."
Do you use such special core material, or is it an "ordinary" ferrite material ?
Do you have the type number of the core material (and are willing to share) ?
This is certainly interesting, and deserve more work.
Also consider the use of Hectors diode plug, as the fundamental frequency is probably not in the MHz range... or take a look at Dr.Stifflers SEC exiter, make a "L3" coil fitting the operating frequency, and remove your AV plug, mount "L3 instead and put the AV plug at the other end of "L3", just a suggestion
At Stifflers homepage are some documents on coil construction and measurement methods relevant for further work.
No I have not seen this, I will have a look, I thought the Doc: was only sec, I did not know he has published other things.
Just uploading two more videos which are in relation to the Anisle circuit, above are the test results of those two videos.
The next will be with a return to the battery, maybe we will get a self runner
Have not got much band width today so they will take time to upload, will post the link when I have it.
The AV plug is only to show the complicated phasing in this circuit. The transformer is out of a TV set that I had, I have 4 in total, two off which are vertical, they are called a phasing transformer and are usually marked as Hi-POT, which stands for phasing out transformer POT.
Hi Mike, Just thought I'd observe. I have done some stuff with transformers before and I believe Hi-POT is a warning for High potential meaning of course high voltage -- like "don't touch me when I am in operation in the TV you took me out of or ill shock the pants off of you."

Just my two cents...
Hi DaemonSlayer
For sure there possibly be a high voltage but if you look how the are wound they are wound to change phases, they are phasing transformers. I am wiring them up different to how they are normally used.
If you look at what I started with in this thread with the switching, no input circuit, which is Naudin, I was looking for a ready made phasing coil for adding an input and this is what I have found.
I think in the future I will make my own in a large form so as I can get down to some serious POWER
The core material is ferrite, I do not think an iron core would work
Sorry if I was unclear. I meant not to dispute that this T is phase editor only that the HI-POT was a warning for high potential

which can be of course ignored if being used by informed hands which take the necessary precautions when handling such devices. On a second note can someone tell me the major differences between a ferrite core and soft iron since these are (I believe) both made principly of Iron (FE)??
Sorry if there was any misunderstanding

Iron is ok for low frequency such as 60hz but you need ferrite for higher frequencies
Watched the video ( by the way!) and was wondering what the reluctance of the resistor is at that frequency given that you know the resistance is 10.1 ohms.

Hi Eric
That is fantastic, it is nearly the same. I have got my inspiration from JL Naudin and had the idea of using phasing coils as that is what I have ready made to hand.
What I need at the moment is a good scope, but it will have to wait or I will see if I can borrow one.
There seems to be extra energy in this circuit, it seems a simple circuit but there are some very complicated things going on inside it.
