  Itsu:
  Great to hear from you. It's good to know that I'm not the only one in the world replicating Geo's crt.   It would also be nice to hear from Geo, one of these days...

   I've had an overheating problem with my system, so I'm using a 10v, 1.5  amp wall adapter to tune my system, until I find the right combination of caps, chokes, wire turn count etz... that is optimum. Although each time I change something, the whole crt responds differently as well, and the same caps won't work as they were previously.

  I use egg shaped magnetite magnets on the yoke core to vary the frequency, or reduce the ringing noise to bearable levels, or even to no audible ringing level, (at least to me).

  The IRFP260N mosfets are doing a good job of producing useable lumin levels, but at the cost of higher amp draw, which is partly the cause of the heating of the Fets.
I'm not using any zeners at the moment, as I can't find the right ones. But, when using only a 12v battery (or less voltage), they may not be absolutely needed.
  I use three different chokes on my device, as that is what is giving me the best light output, and voltage readings. I don't know what the amp draw is, as my analog meter is not working on the amp scale. Nor can the voltage output at the bulbs be read as well, as meter is giving false readings.

  I'll be connecting the Akula yoke core set up, soon, to see what the differences are, also. And later going to build the RMG, using a flyback core, and air coils, with ferrite pieces inside the pvc pipe. 

  As my main interest is in making a feed back path, not just an inverter crt, I'm still needing some advice as to how to go about it. I don't want to blow more fets in the process, as I only have 6 of them.
  Anyway Itsu, good luck to you and anyone else that is participating on the RMG circuits replications.
  I'll be posting some pics, maybe today, as well as a video, when I have more to show.
 
  Back to tuning for resonance...

Dear All.

Any ideas as to what is going on here ??

Cheers Grum.

Dear All.

Further observations.
I have carried out further tests based upon the video I posted yesterday. With the demise of my VERY expensive HT flyback !!    I resorted to another HT source, un rectified this time. No result !!
It would appear that the effect is only present with a DC HV output. Does this lend credence to Tesla's radiant energy ?? Could our wire be acting as an antenna ??

More tests are required, any takers ??

Cheers Grum.

Any suggestions on how to protect the gates?

A 0.1uF ceramic cap across the zeners (= 0.9 Ohm reactance)?
Replace the 470 Ohm resistors with inductionfree/poor ones?
something else?

Thanks,  regards Itsu

Itsu,

What power rating are your zeners? I use 15V, 5W but faster 15V TVS diodes would be an even better choice. The gates get clobbered on a Mazilli. You could also try a couple of ferrite beads on the gate leads placed close to the mosfet but a power zener clamp should do the job.

Thanks Nick,

I too like to hear again from GF one of these days 

i am done with these 47N60C3 MOSFETs for the time being.

Back to the IRFP260N's, but as shown earlier, they do not show any abnormal (cold) energy allthough the circuit seems to work in 2 modes like i mentioned before.

"normal mode" when using a normal sized choke 230uH with 600nF cap. @9.7KHz
"special mode" when using a bigger choke 5mH with same cap. @3KHz


See the pictures of the scope screen shots in both modes (yellow/blue = gate signals, purple/green = drain voltages)

The "special mode" is much more chaotic and makes the MOSFET's heat up more (more current draw).


Good luck,  regards Itsu

Hi Grum,

i cannot match the shown diagram with the video.
To me its looks like 2 different circuits, like where does this capacitive wire comes from/goes to?

Anyway, my guess is that you have an inductive coupling into your bulb.
The flyback is already DC (it has internal diodes), so running it through an external diode again will not add much.

And, those crocodile leads are not meant for HV, so please be carefull when using them in this situation!
Use pliers or something else to handle them

Just my 2 cents 

Regards Itsu
