I do not know what output you have in mind.
What are the respective frequencies of the two 555 astables anyway ?

Hi Verpies
I just want to drive my mosfet gate with this pulse train. Frequencies are about 20KHz and 300KHz. I asked about the operation of my mosfet, if it would experience any implication due to the unsychronized oscillator signals at its gate. I don't really care if the first or last pulse of the train are not complete in duration. I care about the clear on/off switching of my gate.

ps. By the way, after resetting 555, needs some time for the oscillator to start again, and this makes the first pulse of the train to appear a little wider in time than the rest pulses.

- this  is bifilar winding is wound three wires, and
push - pull (generator)  ... and, excitation from kacher
first when the generator is turned on   Lamp is very poorly lit,
with Kacher - bright..
oscilloscope: a first signal from generator, -  second from Tesla..

Thanks for the info!
I understand is a bifilar Tesla manners not Hooper with three wires, that means  three-filar.
Push-pull at 400 Khz , is not much for the yoke?

So you can use the CD40103 chip driven by one 300kHz oscillator (e.g. the 555)  to have a 20kHz pulse train synchronized to it.

I care about the clear on/off switching of my gate.

So you need a strong (several Amperes) driver chip attached closely to the MOSFET.
I also recommend between 16V and 18V gate driving voltage.

Interesting IC! I'll might give it a try at the future, as I already finished this board and tested today. I had to go to 16-18V as you said. Thankfully 12V were enough for the frequencies I intent to use it. I used again gdt. A tc4420 drives a primary through a 4.7 ohm resistance and a 1uF tantalum cap. But I see some oscillation over the  signal at the begin of the 12V pulse (tc4420 output). And this oscillation is also being restored across the secondary. I suspect transformer leakage. But needs to be examined.
