jack... i duplicated the effect and saw that this circuit resembles a current multiplier scheme as a parallel LC tank circuit is. In energy terms i did not find anything extraordinary.
And YES, i urged all experimenters especially to care about different bulbs brightness. This is quite deceptive.

for example.


i took my variac and one 75w 220volt bulb in order to flow some 0.1 amps in order the lamp to light faintly. This happens at 40 volts more or less, thus outputing the bulb some 4w. But if you pass this in your device and the 0.1 amps are of 220v tension is some 22watts (almost double). Assuming a P.F. of 1 then the second bulb will light far far more.
...

Did you actually MEASURE the current ("some 0.1 amps")?
Did you actually MEASURE the input and the output POWER?  If so, what were the results (numbers)?

Would you provide a photo of your set-up?

Good find there Professor.  While fairly low wattage it's a decent price to check this out.  I'm actually astounded at how much they want for isolation transformers these days.  It's crazy.  I know copper is expensive but some of these places must think they are using gold.  Allied Electronics is a company that's been around forever - I was buying parts from them 50 years ago (maybe even 51   ).

You're welcome, E2.  Hope you will do a build on this system. 
I went ahead and ordered a pair of the $18 toroidal trafos also (shown in post above) --likewise from Allied.

Hi Ou dot com Crowd(?),

Yes, measurements, please!

In spite of some 'natural(?)' laziness, perhaps (certainly?) due to too much
pathetic failures and disappointments, I'm still game to test any device that
looks not too much over my building abilities (and my suppliers addresses, BTW).

My failures list is huge.
My motivation is still here but dimming.

Once upon a time, I even was told that one of my (poor) "device" might be kinda 'OU'.
Unfortunately, I promptly and definitely was informed that, over some meter
inaccuracy, it was not the case (= No 'OU'! Move along. Nothing to see)...
Can you imagine the disappointment of an 'OU' moron such me?

However, I'm also still game to spend some monies purchasing (in)efficient(?)
stuffs that would end in some garbage box when I die.
I just want to be enough sure that this new purchasing would not yet be another
useless spending.

I already have 2 small 1:1 trafos.
I would be delighted to consult any -as precise as possible- measurements protocol.

Hello All
I tried this morning with the single isolating trafo design.
But my trafo is too big.
1.5 amps idle current.
I am not sure if I can scale the whole thing up to this kind of size.
If I can get some big bulbs I might give it a go.

Glad to see others are jumping in on this build.

1.  Which circuit to build, actually? 
Here I'm looking at building Jack's attached circuit, with or without the cap shown.  Probably will start without the cap at first.

2.  How to measure input and output energy? 
Since the power is drawn from the mains, I think a straightforward watt-meter can be used to measure the input power.  If the output power is approx 60 Hz, then I suppose another watt-meter (across the load) can be used to measure the output power.

Any comments on the above would be appreciated!
