   Ok, you have a fish wave form, also. But, why do you think that it's due to a standing wave?   
   Can you place your fish wave form to fire in the valley of the inductor's sine wave, as Stalker does?   Any better output or sync when using this fish form, compared to a normal looking sine wave.

A lot of us have had the fish wave, does just one swallow make a summer?

   
      Only a single fase wire is enough to light the bulb?
   

No Nick. The ground wire is used as a phase return. That's why its so easy to fake a self-runner.

Guys
That is just not the "fish" wave that Stalker and Panov speak about.
The "fish" wave is the modulated signal that is formed having as carrier frequency the low KHz component. Nothing to do with Katcher and high frequency. We should see this waveform across the cap inside the current loop.
Watch again Panov's videos. To my eyes his device looks genuine. It is not even "his" device. It is a device that bought from Ruslan...

The "fish" waveform there is from unstable interaction between LC frequency from grenade outpout (when you start seeing waveform jumping up and down) and the frequency from push-pull.
Sergey Panov did show fake device and he said that many times in his video.

 Also because the whole thing did cost him 2 years to the point the most of his videos is about that topic. And from the doctor profession he had to learn radio-engineering to get to that stage.

In this video the puls frequency is variable and the position of the puls coil is variable . And also the capacitor parallel to the puls coil is variable.
By changing the puls coil position the shape of the signal changes .  and also if you vary the cap.

   Ok, so where then is the positive phase grid line when the external input source is disconnected? 
   If Sergej bought the thing from Ruslan, why would he be trying to show a fake working device, running from the grid? 
   You guys are too quick to judge.   
   Same thing happened to Akula, when trying to show the device in Germany. Does that mean that the device is no good?   
   Sergej should have returned it to Ruslan, to see what's up with that. And asked about a guarantee, and at least seen it running, before he bought it, for $5000.There is something very strange about all this.

As you asked  here is translated quote from Sergey Panov video - "After demo I needed to go to other room and my wife was left standing to device. Then Ruslan started to do something on device and preparing it for packaging. Then I heard my wife calling me to look on what Ruslan was doing. Something was off. When I came back to the room the wires was already disconnected. ... Ruslan gave me piece of welding cable with attached connector for connecting rest of wire. He did not give original wire which was connected to device."

When not knowing Russian language things like that are missed easily, heh..

Cheers!

   Still sounds fishy... So, in the demo Sergey could not see another positive grid line going to the device? Was he blind... or was the ground line the only line that could be hot, but it's not hot, since it's suppose ably the "phase return" line.
So, then... where was this trick hot line that makes it all work? We'll never know anything for sure.
   Any ways, just trying to get a feel for this, as it's the last of the self running videos. Only maybe Ruslan has posted something new after that burp. Maybe it's the real deal, this time.
   Such a deal at $5.000,  1/2 down, and the other half, IF it works,  or not.
   I'll sell you mine for only $2.500, works just as well... just needs the right hot ground line... Only one line, works wonders.   Thanks for the translation T-1000.                                                       NickZ

Arunus, a few pages back 'Soliman' posted a schematic as well as the
Sergej Panov video pointer.
I was wondering if you noticed the wording around the Katcher winding

This [частота качера  частота бифиляра]      please explain what he is on about ??
I'm really surprised no one has raised this statement and its actual puzzling meaning here.

Just where is this ''частота бифиляра'' ?
