Well I wish that I could control that condition, because when it happens it allows for much greater output, from the same fixed input. The overheating of course can cause transistor failure, but I had it going that way for a while.
Now it is not doing it (kicking in) any more (which I am missing), as I'm using a different transistor. Nor am I getting the same output levels in the normal condition, as before. All transistors vary somewhat in any case, but keep in mind that my circuit is feed back to the transistor control, battery positive rail, or even to the earth ground.
The point being that when the circuits kicks in, so does the ringing, vibrations, and transistor heat. The stronger the ringing, the higher the output. Which my daughters can't put up with, or myself, for that matter.
What you may be hearing is similar to an AC transformer hum, which may sound similar to what Akula is mentioning is coming from his yoke. I hear a ringing, he hears a hum. May or may not be the same kind of thing, possibly only a matter of degree, as ringing may turn into a vibrating hum at higher output levels.
Like when the grid power line transformers sing their last dieing death song... bagh, bagh, bagh, and out she goes.

You may also have noticed that your cap gets hot when the coil is ringing, so make sure the cap is voltage rated adequately as the p-p voltage rises considerably! Also, use polypropylene type caps with a DC rating of at least 400V and preferably higher.

Menof:
I have made it both ways, and have not noticed a big difference, but as I'm trying to replicate the akula video as closely as I can, I'll continue to use the center tap for now, to see if I can hit on whatever it is that makes a difference. Previously I was just using a single layer white wire as the primary, instead. Which is still on the yoke, to be used as akula's has his also, (with open ends). Hard to tell if that wire is connected to anything or not, but maybe you are right and it goes from the 220v input to the yoke, and back to it, to close that circuit. That would explain some things. The main thing is to be able to get that surprising output, that he is showing. There may be more than one way to do it.

Hoppy, I have not used or needed caps up to now. Did you watch my video that I just posted?
The only component is a transistor. I love simple circuits. Right now my circuit is running as cool as it can get, and very brightly lighting the 110v 7watt incandescent bulb, which is my test indicator.

Yes, I've looked at your video of the Joule Thief. Try a winding on an enclosed ferrite such as a double E-core or toroid for even better efficiency.

What is your next step in your progress towards self-running?

I have wound many toroids, round air cores, yokes, and other circular cores, along with E-cores, and even iron transformers, they all work, and work well. But, the toroids and E-cores ring the worst. Air coil don't, at least not much. Ferrite cores have the most punch and current output, per volume, but their ringing at higher outputs is hard to take.

My ongoing Akula replication is what I'm currently working on. It's the toughest build of all. As no one really knows how it works, or can replicate it, as shown. Before trying for a self runner it must first run, and produce good output, at least 100 watts, or more. Then I'll try to feed back path as shown. I've already wound the feed back coil on it, but need the two bigger AC caps shown, or maybe not so big.
I'm sure with time more information will be forthcoming, especially if there are really hundreds already working in other countries. Or you can just wait and buy it, when available, now that it has been sold.
Thanks again to all our Russian speaking posters, as without them this may not be possible.
