HI TO ALL
THIS CIRCUIT IS VLF AMP HI POWER.If you agree.'ll Talk about this circuit

Hi.
I am interesting to learn more about it.

This circuit can be used to send signals up to 400 meters.The input signal is a square.This circuit has a frequency of 8 to 10 kHz 10 to 15 watts of power.I believe this circuit is very suitable for lrls.

Can you put the values of the components???

Thanks Mustefa.
I am afraid that the 100R at the gate of Mosfet is wrong...
It makes a voltage divider by 1200....

What is your opinion?
This circuit can help FOR LRL?

With proper component values it should work as a VLF power amplifier.

Most VLF LRL's, it doesn't matter whether the transmitter is turned on or off. However in this case the power level is potentially high enough to be hazardous, therefore best to use it turned off.

I think it is very appropriate for lrls.Because the signal is spread through large coil on the ground.
A Question:
What is the current consumption of the circuit?
Do not use the capacitors for Teun out?
