Hi Marco,
this is probably an error that is related to the forum software still having a few bugs.
Also I did not yet find a solution to this error,also not yet at the SMF forum programmer website. Regards, Stefan.

Hello all,

my last post dissapeared. I will try to explain again what Im doing.

I wound a 9 turns collector with lamp wire. Dimensions well known: inner diameter 4", outer diameter 6".

I looked at my coil and got an idea: why not try to pulse just 1 strand of my lamp wire and on the other strand to connect a 100W bulb. So I did it.

On 1 strand the pulses and the +12V from the power supply and on the other strand a bulb and in paralel a 47nF/1kV capacitor. Without any control coils!!

I used just 1 frequency. The highest frequency range from my oscillator = 100 - 300kHz.

At the frequency of 245kHz I had a "success". I saw little sinuses forming from the kicks and then I saw the voltage/current rising. Of course, the light was getting better and better. A just little move of my frequency and the voltage rised to 40 - 60V and the current to 2 - 4A. At this values the bulb lighted at 100W. I also had a vibration of the signals on my scope at 5 - 10 Hz.

Then, yesterday I builded another 9 turn coil, the same as described and connected this 2 coils together.
As I have only 2 MOSFETs (others blown), I pulsed 1 coil with 1 frequency (range 1 - 10kHz) and the other coil with the frequency range 10 - 100kHz.

At some point I got the same "success". This time only the current rised to an unknown level but the voltage was stable = 12V. I didnt had the well known vibration of 5 - 10 Hz this time.

As I lost in the last few months a lot of MOSFETs ( over 50, no typo!!) I decided finally to build TUBE OSCILLATORS because I see NO CHANCE to continue in my research.

My power supply for the TUBES is reday.

Otto, I do not understand "connected together" ?
Do you mean physically next to each other - or do you mean a galvanic connection ?

I think you have two 2-conductor wire coils of 9 turns each. 

• On 1 conductor of coil 1, you have +12V pulsed with FET at f1. 
  
• 
  On 1 conductor of coil 2, you have +12V pulsed with FET at f2. 
  

You have 2 output coils, independent and no galvanic connection.

It would be possible to connect these two output coils in parallel or in series - or leave them independent.

Do these two output coils have the same scope signal - or - do they have different waveforms?

Is this simply a HF transformer converting primary energy to secondary energy ?  Or is there something special with this configuration?
