In order to make reliable observations of electric resonance
effects it is very desirable, if not necessary, to employ an alter-
nator giving currents which rise and fall harmonically, as in
working with make and break currents the observations are not
always trustworthy, since many phenomena, which depend- on
the rate of change, may be produced with widely different fre-
quencies.

you might be right.

but, to me, the above quote does not say i am wrong in my thinking either.

using a relay, or a rotary switch, to create pulses of current also create "distorsions", switch bouncing<---link, in that current.

an alternator will give a smoot signal.

There are 4 ways to connect 2 coils in series and 2 in parallel.

Have you tuned the toroid ?

With a pot ? Check with different jt coils config.

I know you made exhaustive test , but did you ever tried my way tuning the pot every time you change the coil config, i made test with many caps , so far they are good for saving energy , lowering the amp draw.

But i never got better voltage then what my pot test gave me , so i guess my way is just faster .

You may not have enough on the jt side.

If all the loads are identical, then the load is shared, if the load is heaver on one output, it drains some of the other 3 energy from them.

the loads matter in a specific way.

remember what mk1 posted a while ago.
the current is always the same in all coils no matter the loads you put on the coils or on what coil you put it.
the coils are "resistors" is series.

the true definition is: they are impedence in series.
the total impedence change with the load(s) and/or the frequency.

I am afraid I do not understand your request.

You want me to pass the earth frequency and voltage through the toroid using one winding then look at it through the scope through another winding?

Are there any special numbers you have in mind? Just straight winds?

It will soon be dark.

I will see if I can find one or very quickly make one and have a peek.

ok MK1 if you want to pass the EB energy through a coil and collect the energy on the other coil then i can say i had no luck with it. but it could be my torroid

Yes, I only posted 3 but there are 4.

Have you tuned the toroid ?

I tuned it a lot with wires. and turns. I could not even get this big one to turn on at first and after I got it to turn on a BJTLed I stopped. Then I added the MK1 secondary.

With a pot ?

Not yet.

Check with different jt coils config.

What are different jt config?

I am asking if the voltage always goes down to half of what it was.
Why should the tuning stop the secondary from canceling itself out? More than canceling out. adding the 2 sides made this less than the first  half in series and 1/8 of one half in parallel?

What I am understanding from this answer is that sometimes the voltage goes down after the second half is wound, but only if the primary is not tuned.
Is that correct?

I know you made exhaustive test , but did you ever tried my way tuning the pot every time you change the coil config, i made test with many caps , so far they are good for saving energy , lowering the amp draw.

But i never got better voltage then what my pot test gave me , so i guess my way is just faster .

OK
I will try to tune it with a pot with every turn.
I must not understand what you are doing,  so I will just try to do it and see what I get.

You may not have enough on the jt side.

I will try more jt turns even though the voltage has dropped every time I have gone to a higher number of turns.

Let me ask this:
Did you ever see the voltage turn and go higher as you add more turns? I mean after it was first dropping?
I will try that even though it does not make sense to me.

thanks,
