Hello Slayer 

Your last vid was great.  There's real power there!!!  Very nice

Thank you Stprue.

The circuit for it with the coil specs is on page 845.

I just seen your video also very impressive.

There are 4 pin on the trigger coil you can see in the picture the one that isnt being used.  One one led you can see that doesnt look like its being used is goin to the + rail. 

I have not tried a JT yet. (This circuit is not a JT it is similar....kind of)

Not sure how many or distance yet I have just started playing with this circuit.

My vid  shows what I was looking for in this circuit   

It looks like you are only using two pins on the trigger coil? The HV on top and some pin on the bottom? Where and or how is the third pin hooked up?

Thanks!

I think I will stick with the basics for a little while as there seems to be a lot of odd things happening with this circuit!

lol, I just dont understand how to power it? As in how do you hook up the trigger exectly? To what pin goes what and how is it marked on the bottom? I am going to oder a few to replicate it but I have no clue on where to power it? As in it must be so basic its confusing me. I understand one wire goes to the HV on top. On the bottom 3 more wires live.

One of those wires you do not need to hook up, but how is it labeled? Where is it located? The next wire is where the + of the battery goes correct? And the last wire connects to the base of the transistor?

Thanks so much.

@ altrez

You can power a JT in other ways....this one never cough on but I though it was pretty cool.
