Welcome the the JT topic and thank you for the info's.  What is your interest in this forum so far.  Have any of the topics caught your eye?

@ stprue

Will doing this drain the battery faster?

Not necessarily. Power out in watts = amps x volts. You can have more amps or more volts and still have the same power. But, how much power goes into the pickup coil depends on load and number of turns. So changing turns may change power going into pickup coil.

 Hi stprue

Thank you for the warm welcome. I've been following this thread since it's inception and am basically a silent replicator of various Jt's and Dr. Stiffler's SEC. My results have been echoing some of the replicators like xee2's designs.
However,sadly my job and family responsibility cut into the prescious time it requires to do more experimenting with these circuits and wish I can contribute more and so I really appreciate all of you regular  contributers of this thread with your expertise.  Believe me , when I get home from work , I can hardly wait to get to the work bench. You guys and Gals are great. Keep up the good work. I'll be following along with you. Thanks Again.

yes welcome to the topic ...  and our world of insanity meets reality ... 

lol

i hope if you do find some time you could post some pictures of your effords for every one  2 see as pictures are so nice to see ...

btw dont mind my spelling ...  lol   

any how i got the npn pnp 4x1 x 4x1  and 8 8turn mk2 picup coils all wound on a 1 " toroide .. 

it turned out darn nice ...  i thought anyways ..

have not ran it yet but i do know the result of a 6 way split in 1 dirrection ...  so i would expect the same in the other but   who knows ...   

here is a pic of the finished coil

ist!

incase it wasnt all that clear in my last rambblingggs lol   

this is a 2 phase 2 dirrection jt with 8 bidirrectional picups wound inbetween the electromagnets (jt coils)

Thanks for the infos...my goal is to change the power output in the JT so I can use it on more then just lights.  Also I think this could help find the way to better efficienty.

Thanks again...Stew
