@Yucca

Now i know i am not strong on theory but when i think about the way the secondary is wired in parallel and then think about a conventional transformers secondary then i would imagine that they are subtractive and the net result would be very little output.
If he used 2 20 turn secondaries and wired as per a conventional transformer secondary we would get double the current, so i wonder if he has made a mistake in the drawing after all he does show 2 separate secondaries not 1.
My guess is that he is trying to receive 2 units of energy for every 1 unit he puts in less losses.

OR

Even more interesting is the position of the center tap, in the circuit he shows the top half of the secondary is 1.29 times the size of the bottom half of the secondary.

Peter, in one of his lectures Smith states that the part (half) of his secondary with the shunt has the function to get a better "signal" and the tap itself is supposed to provide a negative output/electron inrush path into the circuit (the factor that makes the amperage).

He repeatedly emphasises the center tap as the amperage-factor in his lectures/literature and points to the center tap in the NST as well as the center tap in the receiver coil and also the center tap in the output transformer coil.

The amplitudes of current and voltage are probably dependant on nodes/antinodes which have a specific position at resonance (at the ends and in the middle)
as well as other physical conditions inside the secondary circuit.

I have noticed that too, it is as if he wants to indicate an asymetric voltage divider.
However we have to keep in mind that Smith/Tesla/Marks etc. all want to deceive replicators .

Same old problem, shame the photos don't show where the center tap really is or at least verify the coil configuration.  :'(

Still i guess it's possible to try the different configs

Maybe these 2 pics show it better? It actually looks to me like an exact center tap, which would make most sense antinode-wise.

Ah and to prevent any confusion, there is NO accurate schematic for the table device.
The schematics found in the pdfs differ from that device in some ways.

Are you intending to replicate exactly that table device?

I have noticed a peculiar behaviour, perhaps someone can explain this asymetry?

OK, again operating with the secondary ends connected across bridge. gap distance kept the same in each case. Centre tap ignored. I was counting gapfires per second (gf/s) using a 20 second sample time:

==============================
When all of the secondary is ungrounded:
0.80 gf/s

When I ground the base of the secondary:
5.20 gf/s

When I ground the top of the secondary:
2.90 gf/s

==============================
then I reversed polarity of the primary coil and saw this:

When all of the secondary is ungrounded:
2.10 gf/s

When I ground the base of the secondary:
5.80 gf/s

When I ground the top of the secondary:
3.50 gf/s
==============================

These results are strange, why does grounding the base of the secondary give much higher output energy regardless of the polarity of the primary excitation?

Again I must also say again, the gf/s increases from a slow rate to a higher stable rate over the course of maybe 20 seconds. And then if you leave the device off for a few minutes you can see the slow rate on startup again, it really is weird, if you turn it off for just 10s then it starts up fast again. Could this be some aetheric inertial behaviour perhaps?

But always when I switch back and forth between top and bottom grounding I see a large difference in performance.

edit:
This is a radio circuit really, so maybe the tuning changes lots depending on slight adjustments, it's certainly got some weird behaviour and power outputs can vary greatly.

wow those pictures are handy did i miss some information posted somewhere?

OK this is making more sense now, so we know there's a cap on one side of the secondary, so we tune the primary and the secondary also.

now we see  a cap across the top half of the secondary and i cannot see a wire connecting the bottom half so i would guess it also is linked back to the top as per the diagram, so both halfs are indeed in parallel.

It is also interesting to see the construction of the coil, he uses 2 different sizes of tube, the inner has the primary wound on it, and he uses  2 seperate half length tubes, one for each half of the secondary and they each push onto the primary tube, we can see 2 wires connecting to the connecting block in the middle tap.

Now i would imagine the grey boxes are high voltage caps, although i would have expected to see diodes in there place, not that familiar with real high voltage components so i could be wrong, so wheres the diodes.

@Yucca
very interesting with the gf/s
Not sure what it means sorry.

i have now finished building my HV psu
I already have a loptx based supply i built some time ago for lifter tests.

but have been bringing together stuff i built for the TPU.
My new psu uses a blocking monostable driven from a signal generator followed by a 5 stage multiplier, i wasn't sure if i would get the current to produce a good enough spark but it seems to be ok i think.

Here's a video
http://rapidshare.com/files/270666679/BlockingMonoHV.asf

Although the mike doesn't pick up much of the spark sound it is quiet loud.
The current draw is low about 13ma at 90v supply voltage and the rails are clean.

@Yucca:
Good to have some epiric data! Nice one.
In the TPU the orientation of the coil was important.
Upside down it did not work at all.
Maybe the orientation of the coil in your device is also important for its function in a similar way.

@Peter:
Here is a better resolution one: http://www.yousendit.com/download/YkxKOGNkWkJWRDljR0E9PQ

The diodes are there, in front of the HV cap positive terminal rail.
Actually the wiring of the secondary is quite remarkable.
The outer ends are connected together to the high pressure cable (plus line to the cap)
via the rectifier diodes.
And the center tap is connected to the minus line to the cap.
This is different than in Smith´s pdf diagram.
I have drawn a schematic of how it might look like, but i don´t know what these two components are in the top half of the secondary. Probably also caps ?!
Also that feedback unit is not clear to me in its functionality.

The OD of the primary is 2" and the OD of the secondary is 3"
The primary was supposed to be slidable inside of the secondary to tune the device,
but Smith was already tuned even without sliding just by adding two caps.

The remarkable thing about the whole device is that it seems to work with unidirectional impulses on the primary and the secondary with (nearly) no negative amplitude.

Oh man thank you for that image what a difference a good photo makes.

Yes i see the problem identifying the 2 little grey components, they look like high value plastic molded resistors to me, i have never known small caps to be coloured grey before but i guess anything is possible.

That is also silver plated copper wire for the secondary not tinned.

The good news is now all i need to buy is 1 very high voltage high current diode as the output rectifier.

The box you have a question mark over on the output leg is an inductor.

I wonder how many of these components can still be bought i bet they turn up from time to time on ebay.

Cheers,
Peter

Nice photo xeno, thanks, I have not seen that before.

The two unknown components, could they be 2 diodes smaller than the others or perhaps as peter says resistors?

Looking at it I think I see that the primary is wound around the pipe using HV cable in the middle of the top half of the secondary, the device is almost a 3 coil device in a way, it looks like the bottom half of the secondary is where he harvests most power hence the chunky parallel diodes on that coil segment. very interesting!

Indeed it does well spotted, so i guess the primary was able to move the full width of the secondary to find the sweet spot.
No wonder his stuff hasnt been replicated to date it's so easy to miss things.

I have to say with that photo i feel we stand a lot more chance getting this baby going than any of the Tpu's.

Yes the secondary seems like copper litz. I have bought something in a store that looks exactly like it. (It is more suited for RF signals)

The questionmark device might contain inductors (probably two of them) but since this seems to be NOT the output transformer (because too small for 30 kW) i can not
identify its function and what might be inside.
Don Smith refers to it as the feedback system on his website, however it seems not to be wired to the primary-side inverter. So maybe he talks about another feedback than to the primary ?! Something that might contribute to the secondary functionality maybe even ???

Hmm, so you also think that the two little components could be resistors, that was my first thought, but i could not explain their presence at that place in the circuit would it be resistors. Or maybe also diodes? From just the appearance they look like smaller HV caps, something like in the 3-6 kV region and few pF capacity.
The fact that Smith paralleled two diodes in the bottom part indicates that he
has already quite some amperage flowing to the caps.

Nice that you nearly have all components together. Do you also already have comparable HV caps with enough power rating?
Looking forward to seeing your set-up soon ;)

The slidable primary can be seen in the 3rd pic.

My shopping list is changing by the second LOL i will need to get the bits yet, i have already ordered bits, but in light of tonight's info and picture i feel we could possibly do a pretty close replication, not sure about the large grey caps, i don't suppose you know there values, i am wondering if we can use microwave caps with a begging trip to the local tip. Screwdriver in hand LOL

The final inductor device, although it has 2 coils he only uses 1 of them, the final inversion circuit must be a seperate unit which is not present but plugs into the output strip board.

I was hoping to try building a lower power device using lower spec parts but now am rethinking this and thinking of going for a close replication.

I have repaired similar 12v inverters years ago, they were used to power the old camcorders via the mains ;)

I can only encourage you to go as close to the original as possible !
Personally i am staying away from insanely high voltages, thats why i chose to experiment more with downward conversion transformers (like Kapanadze does it)  as it makes components more affordable and the whole device less dangerous (see pic).
Tesla probably got most shocked with this type of devices than with any other hehe.
About the grey caps, i guesstimate them to be 20kV caps of 8-10 KW power rating each. Smith said they were custom made for him, very hard to get otherwise.
I think once you get the device going like intended you really need that huge caps or you´ll burn microwave caps or any comparable low power stuff.
