Sorry Void, My bad, That's 119 uH measured for the coil, the resistor I cannot measure as I don't have a good enough LCR meter.  :-[
My apologies. I think I'll be seeing similar but slightly different results to Tinsel, my set up is a little bit different.

Tinsel has a primary with the resonance capacitors directly across the primary switched by a Royer. But my setup has just a
capacitor across the switch. My primary is not tuned to full resonance, it's capacitor is smaller than it would need be for that
so I get a DC lump of 40 volts which resembles a Half of a sine wave across the drain and primary circuit ground. Then I use
the secondary (tanked and tunable) to get the sine waves and so I can tune for power with the variable capacitor across the
secondary, an output coil can go to the positive end of the secondary and produce nice sine waves even under load, that coil
I tune with a variable inductor in the tank. Tuning the main tank takes the input from idle at about eg. 0.08 A @12.4 v up to full
power which is limited by different things with different loads and input voltages.

From the lower turn thicker wire output coil I can drive transformers or rectify to DC and such things, using a capacitor in series
with a transformer can have benefits as well. All coils have very low resistance except the output coils of the, separate ferrite
transformer which has 0.5 mm wire secondaries, but it's not much R either.

I've got a diode to block any reverse currents to a battery or other supply, this could cause some loss by forcing a higher input
power, due to no return. I intend to use a resonant charging circuit on the primary circuit to boost input voltage and limit current
if it works well. That always tends to boost the input a bit.  :)

The small 12 volt powered fluro driver uses 0.5 A @ 12.4 volts to drive a 6 Watt fluro, and it's bright but it was designed for
8 Watts however I only have one 8 Watt tube and it uses the same input when driven by the same little fluro driver. 6.2 Watts.

I'll be wanting to light 2 x 18 Watt fluro's with my device eventually, one tube the other or both I hope.

Say what?  119 uH for a 0.1 ohm, 5W  wirewound resistor? That seems to be a very high inductance if correct.
Such a high inductance for a CSR at 420 KHz could definitely throw off your scope measurements significantly. If that value of
inductance of your 0.1 ohm CSR resistor is correct and you are aware of it, then it looks like you have deliberately been trying
to make bad measurements to try to make some point?  It looks like you are deliberately running your circuit at a frequency
at which your CSR is coming into self resonance, and thus throwing your measurements way off. However, anyone with a
half decent knowledge of doing scope measurements at high frequencies would be aware of this sort of problem and
take steps to avoid it.

Just for comparison, I have a 1 ohm, 5W wirewound ceramic power resistor and its inductance  is only about 0.7 uH. Anyway, if the inductance
of your CSR really is 119uH, then it might well explain at least a good part of the strange scope measurements you have been posting here.
Sure, a person has to know how to use their scope well and be aware of various potential problem areas to make accurate measurements,
but that doesn't mean that everyone out there is making bad measurements just because there is a potential for it.  ;)
Yes, I know that there are various people out there on the internet who do make bad measurements and thus come to false conclusions about
overunity, but that doesn't make them all 'frauds' and 'scammers'. Some people just are mistaken because they don't
have the proper technical background to realize their measurement errors and incorrect assumptions. Not a big deal to me.
It is a given that many home hobbyists who are not formally trained in electronics or mechanics or whatever they are experimenting with
are going to come to false conclusions sometimes. Heck even many professional engineers and scientists can make measurement
errors or make incorrect assumptions. That's why we have a whole peer review process built into our science vetting process.
Not a big deal mate. It all works out in the wash. Either something really works as described or it doesn't.  :D

Now Void, Buddy I've got non inductive "Ohmite" resistors on the way, if you think I'm deliberately running the setup at a
frequency to cause the resistor be in self resonance, then you're dead wrong about the deliberate part ! And that is a slurring my
name.
Why do that ?

I'm not a half wit I'm just a boilermaker. You think I would use a resistor with 119 uH in a resonant setup like this ? OMG
Get off my back champ. Are you in Aus ?
Wanna come to my house and measure the resistor for me ?  ;D You're welcome to do that.
While you're here you can spend a few hours teaching me how to use the scope correctly, don't expect payment though
and I might get you to help me do some farm work !

You are free to ignore me. But I have no intention of wasting more time. I haven't made any "claims" except sarcastically.
unless you want to pay me then you are not my boss, even then I need to allow you to pay me before that can happen.

Just to be fair, here's another offer, you get whatever quotes of me you want that you think are not appropriate and link the post
they are in so the context can be seen. And I will either defend them or retract them. Otherwise, whats the problem ?

Hi Farmhand. Ok, I would be inclined to think that if you are knowingly using a CSR with an
inductance of 119 uH that you would likely know that this is going to throw off your scope measurements.
That's why I was asking if you were doing this deliberately to try to make a point.

How did you measure the inductance of your 0.1 ohm resistor?
If it is measuring that high of an inductance with a half decent inductance meter, then it may very
well be the cause of your odd scope measurement results. At an inductance value of 119uH at 420 KHz,
it could be at or near self resonance which can give the kind of strange phase shift and unusually
high scope voltage readings you are seeing.

One way to check if a resistor (or coil) is at or close to self resonance is (only if the voltage levels are safe) is to
slowly bring your hand or finger near, or put it right on the body of the resistor, while you are monitoring
the voltage waveform across it with your scope probe, and see if the voltage fluctuates up and down as
you touch and move your finger close to and away from the resistor body. If the voltage amplitude across
the resistor does fluctuate when doing this then your resistor is definitely showing resonance effects.

Anyway, 119uH, if correct, will definitely throw off your scope measurements at a frequency of 420 KHz.
Your non inductive CSR resistors should make a big difference in your measurements if that is the case.


Edit: Ignore the above. I see you posted that the 119 uH is not correct for your CSR...



All the best...

:)

Ok, then it looks like we are back to square one unless someone has spotted what is causing this.  ;) 119 uH sounded awfully
high for a 0.1 ohm wire wound resistor. 119 uH sounds more like an air core coil.  :)  So, if that is the case then I am still
not sure why you are seeing such an unusual phase shift in your load current measurements.

No, I am not in Aus.  I would have to build a similar arrangement and do some measurements to see if I can identify
what is going on. I have seen close to 180 degree phase shifts on the current when sweeping ferrite transformers with different
winding arrangements from low KHz into the MHz range. You can sometimes hit certain frequencies where you can see strange phase
shifts like that, but changing the frequency just a bit makes the phase change very fast back to more normal ranges. I don't know why
exactly that happens, maybe due to hitting resonance points in the transformer windings, but I guess maybe it can happen using certain air
core transformer winding arrangements as well. I can't recall if I have ever seen close to a 180 degree current phase shift with an air core
transformer setup before.
All the best...
