If I had to guess....a capacitor... perhaps this one?

Now that looks like and audio transformer or choke. The reason? Even then most power transformers had a metal shell (even at RS). Many audio transformers or power chokes did not (especially at RS).

The brown binding could be a rubber band but it is more likely the waxed cable binder (waxed string) used by virtually all TV repair folk then and for a long time before.
Great stuff for avoiding vibration problems. If I still had some I would rather use that than spiro-band or ty-wraps.

I believe you may be right Bep...that looks exactly like the audio transformers of the day.

I see a lot of things in that tpu, common with speaker and amp set-ups.

Something wasn't quite right about the audio transformer idea so I pulled out an old ARRL handbook.
Transformer color codes (at least standard ones) did not use white wires on the primary or secondary, slate either.
Also I don't recall ever seeing white wires on the secondary. However, slate, white and other light colored wires, of the same color, were used on power chokes. (the type generally found between the smoothing caps on the B+ line)
Red was common on the B+ line after the rectifiers. Slate, yellow and white were found on switching mode power supply output filters. Almost all are now toroidal or cylindrical. Then they were still seen on E cores and would usually only have two leads.

I had to watch the DVD again  :P I still don't see active devices of any kind - Tranny's FETs etc. The three legged device looks more like an epoxy dipped booster coil (they looke identical to flat radial lead mylar caps except the leads could be heavier and they had color bands or dots for coding.

as slapper suggested, it looks more like a HC-49US crystal, but decide for yourselves

OOOOOOOOOhhhhh!!!! a crystal!  Whoa!  Stop the presses!

either could  produce "sustained oscillations"


On the open-TPU - the second one - the bifilar wires - where is the collector?

The square things that SM places magnets on top of - why are these wrapped in tape?  What sort of device has this shape?

litle square thign with like 4 coils on it.  magnet was used to bias it.   of corse it is covered with tape so no one can see it.

I don ;t think SM was given the tech or stole it or copied it - he stumbled across it and pursued it.

much simpler ways I suppose - at least wud seam so.

That looks like a  crystal to me,  but I have known to been wrong approx 77.4938% of the time.

@slapper

Crystal was my first choice also. This will  have to be tested. What advantage would a crystal have over a capacitor in the FTPU and what is required as peripheral components when using a crystal.

@BEP

I have been looking at that component for a long time now and I think it is simply a four pin bridge rectifier. There are two ring wires one from the top and the other from the bottom ring going there and then two wires leave it and go to the output.

I really did not want to see the crystal. The crystal goes against my line of thinking of this thing. A crystal usually requires some active circuitry and it infers higher frequencies (1Mhz to 100Mhz for that particular package) at relative stable tolerance levels. The active circuitry could involve a transistor or fet or logic; none of which is visible to me. A very common frequency in this package is the color burst frequency.

Take care.

   If sm has a current going round and round he needs to convert it to voltage  somewhere along the line.   Using the Hall effect to make an ammeter that converts the magnetic field change to voltage would be one way.   He uses a handheld ammeter like mechanics use to check dc current draw when he is checking out his tapedup tpus.

@slapper

But there is a transistor in the FTPU. I have shown it here;
http://www.overunity.com/index.php/topic,4486.msg94447.html#msg94447

I have seen this transistor is many angles and even upside down when the FTPU is turned over, it lands in the palm of the left hand. There is no doubt there is a small circuit board behind the toroid. On the circuit board, you can even see there is a slow blow type fuse, a transistor, a resistor, two diodes (in short metal cylinders), and a capacitor.

Also right behind the crystal, I think I can see a potentiometer. lol
Would a pot be required with a crystal?

I will be posting my diagram today even though it is not complete at least it will give you guys some advance and I can update it with new discoveries. I am trying to see the direction of windings etc., but it's not easy at all.

ADDED:

@sparks

I read your other post also and kind of catch what you are saying.

I seems that voltage is easy to produce, it is the amperage that has me puzzled. Where in the TPU can you generate amperage. It has to be in a conductor with many parallel wires. Would standard lamp wire apply even thought the standards are not isolated like in Litz wire.

@wattsup

   If sm gets a rotating magnetic field going the collector copper will get alot of current going around in it.  The surface area of the copper will be carrying this current. Multistranded copper has umpteen more surface area than solid.  So my answer is yes.
  The copper lamp cord collector winding becomes a capacitor for the kick energy.  Storing energy in a highcurrent low voltage electromagnetic spin field.  Now you need to get this capacitor discharged into the load or over to the lamps.

@sparks

OK I get it.

@all

Damn upload limit. I have put up an accepted file size drawing of the wiring on the FTPU that I have put up so far. I had to add more things but did not want to wait anymore and get this out there. I'll make changes as required. Sorry for such a low file size limit on the Forum but I have uploaded a larger version here;

http://www.overunity.com/index.php?action=tpmod;dl=get57

In the diagram you will notice three rings colored orange, blue and yellow. I have done this to separate the ring windings. The orange ring is the horizontal loop collector. The blue ring is the first primary vertical winding called the control coils. The yellow ring will show the thin wire coil known as the feedback. Just remeber that the blue and yellow ring are actually wound over the orange ring.
