While the amount of AC on the secondary side will vary depending
on the circuit configuration, it's the DC that will ultimately
drive the LED's. It seems reasonable to me to do exactly
as Nick has done, float a D'Arsonval ammeter on the secondary
side. If the meter is physically small enough, the capacitive
coupling to ground should be small enough to limit the
effects on tuning.
I would not even try to scope these experiments. Not for lack
of bandwidth; hell, I've measured pS risetimes, but because
of the huge impedences on the secondary side. You could make
a good differential measurement and see an accurate waveform,
but the capacitive loading would be so great as to make
the actual measurement irrelevant.
Using the light output on a photodiode or other detector
as Nick and others has done is good, with the important
caveat that the "ammeter" is this case is going to be
nonlinear in it's response. In practice this shouldn't
be a problem but I fear it will/has been for many
researchers. Given what Nick does for a living, I
have every reason to trust his light based measurements.

In a way, I wish he had not posted the Thomas circuit, which does
produce a lot of lighting effect, but lesser current - for whatever reason.
This brings up another point. In the AV load loop(s), with two signal
diodes and 20-40 LEDs which are also diodes, one would expect DC- or
perhaps DC with minimal ripple. But in fact, all indications (and the
posted scope shots) are that there is something else -- which in my
feeble attempt to make sense of it, is attributable to the RF
interacting with a "halo" of stray capacitance which is in the active
"zone" around the circuit. This would be the source of gain - if there
is indeed a real gain. Some days I am convinced the gain is exotic like
ZPE, others more mundane like CMB or whatever. There is apparently a
minimal diurnal effect.
Doesn't this setup kinda sound like an ultra-efficient 3-D antenna,
using a blob of stray capacitance to cohere some type of wave energy ?
... what kind of wave energy? You can rule out broadcast RF - since this
SEC effect (according to everything which I can gather) has been seen in
at least five different locations, one of which has near zero radio
reception.
