@MK!
I cannot understand those concepts yet. I have made a drawing that represents the primary in the jt I have on the biggo. It is not like either of those choices you gave me as far as I can tell, so...
Please feel free to change it and annotate it to explain, if you want to.

@xee,
Thank you, but
I didn't expect a comment about the pickups.

I meant the primary where the larger number of turns is on the base and smaller number is on the collector. and wow it is way bigger in output, but before on other designs or whatever... the opposite was true.
I knew you were working a theory about this. That is why I thought you would comment.

@Gadget
It is a 2N3055 It is printed with RCA on the front.

I corrected the phase?

thank you,

yes remember i told you there are 6 ways to hook up the primary Jt . for example . : two wires wrapped the same time . the beginning  is 12 the end of those wires are 3 and 4  . ok . we can hook 1+ 3 together and then switch the wire on  B an c  with 2 and 4  thats 3 different ways then we could hook up 2+4 together  and switch 1 and 3 between b and c . thats 3 more ways . 6 total . In the 6 ways you will find the correct phase to run secondaries in series and obtain gain rather than cancel . . BTW secondaries have 2 more phases as well . Confused . hehe . you do get the point though ?

I modified the drawing a bit to look at the field lines created in the toroid by the jt coils.

@gadget

The 2n3055 seem so work better at low hz , slower is key with bigger toroid.

I thought we were just talking about the secondary. The pickup.

Here for a review because it is so many words
90 +90 = 80
90 + 90 = 12
boo hiss bad
that was yesterday until I put the many turns onto the Base coil

90 + 90 = 192
yeay

But ta da today...

90 + 90 = 450

OMG!

The 2 differences were more winds on the base coil
the transistor was changed to a 2N3055

So, is that phase?

Thank you, Mark,

Now, is there a way to say what happens with the 3 directional  pickup as you do it? When added to this?

The thing to add to this question is that the ends of my pickup are starting and ending on the bottom of this drawing. (there were reasons, but I want to be sure you realize this)

@ Jeanna

Some more to get a better picture.

Yes i realize It !
