No it don't, if you count that each coil has 200v and the botton of the secondary is the earth, you have 200 + 200 so va =+400 and the vb also + 200 so between va and vb is 200

Do you not understand what Potential Difference means? You can calculate it in two ways, |Va| + |Vb| = Vab or Va - Vb = Vab.
Example:
Va = +200v
Vb = -200v
|+200| + |-200| = 400v
(+200v) - (-200v) = 400v

Its the same way that how house AC power system work to give you 240vac from 2 phase 120vac power systems. The phases are 180 degrees out of phase and when you combine them you will get the 240vac output for appliances such as electric stoves.

Tonny,

Pay attention the polarity of the tx5 choke is reversed.

The first choke sends a positive in relation to ground added by the secondary also positive. 1+1

The other choke also sends a positive pulse in relation to ground so 2-1 =1

Is like if the outer tube is 400v above floating ground

the inner is 200v above floating ground

and there is 200 between them...

Theres no 180° nothing... simply voltage canceling each other out... I go 400 meters in one direction and go back 200 meters, the total distance i walk is 600 but i'm only 200 meters away from where i start...

Potential exists relative to a point.

This is what all stan drawing with coil orientation are saying , not me!

can L2 be 90 degrees out of phase?

Don I agree more with what you said:

Quote
As for resonance taking place between choke 1 and the cell is where I see it differently.Yes resonance will take place there,but most of the resonance is in choke coil 1 itself.The capacitance in the choke is far greater than the cell.When you tune into resonance,disconnect the cell and see what happens.You will see a voltage drop and the frequency will need to be reajusted to get it back.This happens because you removed the small capacitance of the cell,but it will still resonate without the cell.

I have been thinking the same way about the VIC resonance. The choke resonance will form a parallel tank circuit with a very high impedance limiting current. I don't think the water capacitor is part of the resonant circuit but it causes the ANTIRESONANCE phenemenon to occur which will cause the resonant frequency to change. (Ref http://www.allaboutcircuits.com/vol_2/chpt_6/5.html ). I think this is why Stan reduced the size of the water capacitor to the injectors size, to limit antiresonance as much as possible.

I just don't see how the resonance can be taking place between the L1 choke and the water capacitor because there is a diode in series. Now coil resonance is a Parallel LC tank circuit. The current flows back and forth from the inductor and capacitor, even with a diode in series the parallel tank circuit (Self resonant coil) will resonate and produce AC oscillations.

Considering the coil is not really a parallel circuit I believe those AC oscillations will reach the water capacitor.

Don,

Sorry if this is off-topic, but how many turns do you have in your vic pickup (feedback) coil?
People give different numbers of turns for all coils.
Here's what I gathered so far:

Primary Coil (Blue): 600-650 Turns 29AWG Magnet Wire
Secondary Coil (Green slim bobbin): 3000-3500 Turns 29AWG Magnet Wire
Pickup Coil (Yellow): 200 Turns 29AWG Magnet Wire
Choke 1 (Red): 3000-3500 Turns 29AWG Magnet Wire
Choke 2 (Red): 3000-3500 Turns 29AWG Magnet Wire

Thanks

Primary Coil (Yellow) = 400 to 500 turns
Feedback Coil (Green) = 400 to 500 turns (same as Primary)
Secondary Coil (Blue) = 3000 turns
L1 Coil (Red) = 3000 turns
L2 Coil (Red) = 3000 turns

The Primary to Secondary ratio is approx. 1:7
Based on the resistance measurements of each coil you will need the follow amount of 29 awg (81.84 ohms/1kFT) wire:
Primary = 10.5 ohms = 128.3 feet of wire
Feedback = 11.5 ohms = 140.5 feet of wire
Secondary = 72.4 ohms = 884.7 feet or wire
L1 = 76.7 ohms = 937.2 feet of wire
L2 = 70.1 ohms = 856.6 feet of wire
