Hi Bill,
Spikes again.
I bet you are right about that.

I am posting the pic yucca gave me on the other thread because it is like a jt with secondary sort of. (on acid...)

@Altrez I think you are connecting to the wrong wires, maybe.
And they do make them with resistors. I was glad to find one without the extra resistor!

I have two without the internal resistor. I will try again tonight =)

This is where I got most of mine:

http://parts.digikey.com/1/parts/90420-capacitor-ultra-10f-2-7v-radial-eshsr-0010c0-002r7.html

At the bottom of this page, you can navigate to other Farad capacities like 25, 100, 300, etc.

If you get into the larger sizes (Like my 650 Farad cap) Gadgetmall has the best deal on them I know about.

Bill

Thank you so much Bill!

jeanna drawing reminded me that often two leads of the transformer are tied together and do not come out as separate connections. In this case I would suggest using the following.

xee2,

Can you explain the black dots on the diagram for me Jeanna tried but I am still confused. I think what I need to do is take one wire wrap it twice around the Toroid then take a separate wire and wrap it three times around the Toroid. Attach the opposite ends of the wires to each other for the + and then hook the other two up as show.

Is that correct? I have made around 100 Working JTs but I never really spent the time to worry about the windings. I always use a 12 / 12 lol.

Thanks!
