Has any one built this circuit and if so how did it work and would you recommend it?

I ordered the biggest fly back core from information unlimited, and i found this circuit designed for a homemade flyback.

is there a frequency adjust?

what tp1 tp3 mean on the right hand side of the schematic ?

thanks

The frequency adjustment is R10 and P3. See the datasheet

for finding the frequency from the capacitor and resistor values. TP1 and TP3 are test points.

There is no current or power limiting in the circuit ...
not only is that circuit lethal
it will hurt all the time you are dying.
