Smoothing was just a generalization.

You are mistaken about all the center choke coils not being in parallel.

Consider that the two toroids in the LTPU. Each pair of coils ARE in parallel. One white wire connects to one black wire and the other white wire connects to the other black wire.

In the FTPU the four toroid coil wire coming from the center are not in parallel. In the Ftpu toroid, the farthest black wire is going to the top control coil, the other black wire is going to EMs capacitor that is going to the circuit board. The farthest white wire is going to the big capacitor hidden between the layers and the other white wire is going to the circuit board. That much we know.

All SM TPUs have a center or side placed toroid coil even the 4 and 6 inch models. We have already been through this many times.

i disagree.

you're making many assumptions but that's your prerogative

and you must be seeing things, because there is no separate visible toroidal coil besides the toroid shape of the 4 and 6 inch devices themselves---you can't be serious right?...been starring in the dark and too long at those videos i imagine 


@Loner

you too are assuming that the toroid potting was an afterthought. well the point i was trying to make and something you might want to consider is that the potting already came with the toroid  , and this particular toroid common-mode choke type just happens to be the one SM had access to

i'm not saying that it's impossible, but highly unlikely that SM potted these himself

Got a quote for you:
"Magnetic Resonance Amplifier
With low-level ultrasonic input signals, the Magnetic Resonance Amplifier (MRA) produces usable direct current power at levels above unity. This circuit is based upon the work and theories of John Ernst Worrell Keely, and is offered into the public domain in his memory.
(from [rexresearch mra article])"

Direct URL to the above: http://rexresearch.com/mra/1mra.htm .. if you are slow on catching, scale up the device and you'll understand you have to lower the frequency - probably down to 5kHz and lower. Piezo transducer can probably be changed to magnetic stimulation of a larger body - the body should posses some magnetostriction/electrostriction property so that it can induce current in circuitry. (piezo crystals are electroacoustic in nature). Terfenol-D looks like a widespread magnetostrictive material (it's good enough to run at frequencies up to 2 kHz). http://aml.seas.ucla.edu/research/areas/magnetostrictive/overview.htm

Note the black (well, actually dark grey) Terfenol-D ring: http://www.activesignaltech.com/Terfenol1.html Looks like a dissected TPU, isn't it?

Loner,

well, i'm no expert on these parts, so i trust your opinion.

let's say SM did pot them himself. he must have had a good reason or reasons.

if the dielectric of potting compound is higher than air, then maybe he wanted to avoid arcing.

potting them would also provide stability to his solder connections to the mag-wire, and this would also explain why there are two types of wire, one on each side. he had the freedom to do it this way.

bottom line is it's not of much importance anyway---is it? the big question is what was he using them for?

@all, can anyone point out the common-mode chokes that wattsup says are in the 4" and 6" devices please?
