JNL is doing a Meyer's replication

My suggestion is to use just hight power switching transistor. By the way u may want transistor what is meant to work progressively.
I just did exams at school and got pretty good results so i pretty much know the thing  .... U should use stabilization transistor (impulse voltage regulator). Because ...
It is hight power it should be fast recovery and it should be perfect for pulsing circuit ...
Any way 100 KHz is not too hight frequency but u need to make sure that u got switching transistor. Area transistor should work better coz it got hight input resistance so u will not heat driving - oscillation (pulsing) part. Mosfet transistor maybe ....


by the way why u try to use induction element oscillator. 555 times should work like charm. They are very accurate and u can change frequency very easily and i guess it is part what u should work on.

According to the circuit, the DC supply for the 4093 should be 5 Volts?Huh.

Yeah, because the output of these nand chips is 0 or 5 volt. A 7905 would work

The youtube video works again.

555's are also very easy, just google "555 tutorial"

And about circuit ...
U cant be so smart to build it up in you head by calculating things what are incalculable.  Use circuit simulation programs like multisim (labsoft national insruments) theres build in 555 timer tool also.

This is going to be it. JLN will have specs and they will work and be public info!!!!! I am psyched.....

TROYD1    THANKS FOR BRINGING THIS TO THE ATTENTION OF THE FORUM    you are right these guys are the real deal  Chet  PS its to good to be true around the Forum things are poppin everywhere
