Some times it's realy odd trying to understand if your bulding a horizontal tesla coil or s transmitter of some kind. I looked at Nick's katcher coil and thought that lookes dead thin wire, for a tuned arial.

Any way i'm going to change the subject here a little, has any one seen this Psec device it's one i found on the net some one posted i'm not sure how it works but the coil is a mains filter type, all you have to do is find out the componts and the input frq and you get more out than in. Think you can solve it, be my guest.
I have played with this type of coil with a component tester and a scope, the way its wound produces a spin in the devices tursion field

   Dog:
   Thanks, but I will probably order some of these fets (below) next. As they are the one recommended by Ruslan.
   The fets that are running on my device now were pulled out, just now, and tested out fine.
   I still have a couple more new IRFP260N, for now. But, these higher amp fets below do seam to be a better choice.

   AlienGrey:  My Kacher's secondary coil has been rewound with the recommended 19 or 20 gauge mag wire. So, it's not too thin, at all. I did originally have it wound with 28 gauge wire and far more turns, for the another project, which lit up my CFL bulbs even better they do now. As there are fewer turns on the current secondary coil now, to try to better sync up to the grenade's running frequency.

Hello everyone, I'm new here, so if someone asked something similiar or if it is silly question I'm sorry, but I have trouble with interpretation of the picture.
In the picture in the attachment picture, I pointed out wavelenght measurements if they are that, I'm not sure.
Now my question would be how do I get these wavelenghts, by which calculations, and are they linked with frequencies in the picture and how.
Thanks for your time

Hello, are these pointed out measurements wavelength measurements or what?
Thanks

Hi Nick,

Some general notice if you do not mind, mainly on the Mazilli oscillator. If you expect to get say 300W output power
from it across a load and the supply voltage is 24V, then the current draw by the oscillator should be at
I=300W/24V=12.5 Amper, assuming a 100% efficiency for the oscillator which it does not have as per 'normal' science.
This means that your new 24V PS would never be able to feed it, even if it could provide the specified 10A
max load current flawlessly. You need more beefy PS than that which are designed to give at least 15 or even
20A output current at 24V. Sorry that such consideration was not a topic here earlier.

Some words on the heat issue of the MOSFETs. If I assume a rigorous 80% efficiency for your oscillator,
as per conventional science,  then at your expected 300W output in the load, the input power to the oscillator
would be 360W. Allowing say 10W loss (worst case) for the output transformer, the dissipation for each MOSFET
would be around (360-300-10)/2=25W per MOSFET.  If you had a MOSFET which has say 1000W rated power handling
instead of the 280W the IRFP260N has, it would heat up to the same temperature provided its specified drain-source
ON resistance would be the same as that of the IRFP260N and you would also use the same heat sink, ok?

The IRFP260N type has 0.04 Ohm ON resistance when ID=28A and VGS=10V. The above suggested IRFB3077PbF type
is much better in this respect because it has 0.003 Ohm ON resistance when ID=75A and VGS=10V. 
However, this type has only a 75V drain to source breakdown voltage and this is a risky low value when the oscillator
is run from a 24V PS.  (A rule of thumb is to use MOSFETs with 4 times higher breakdown voltage than the
supply voltage used.)  I am not saying it would break down at the first switch-on moment but it would be close to it
and on the long run it would be the weakest piece in the 'chain'.  A 100V type would be preferred for a 24V supply.

The ratio of the ON resistances is about 13 (0.04/0.003) this means 13 times less heat dissipation for the IRFB3077
versus the IRFP260 at the same drain current flow, so such a low ON resistance type to use is a good step.
The IRFP2907 has 0.0036 Ohm ON resistance when ID=125A and VGS=10V, so in this respect is 10 times better than
the IRFP260. It also has 75V drain to source breakdown voltage but surely will work.
I think you have now got enough from conventional science...     

Using your scope will surely help explore your present circuit. Good luck!
