@All,

Some time ago I recall that there was discussion regarding the inductace of the CSR (Rshunt) used in the NERD circuit.  In the "paper" it is stated to be 110nHy.

Was this determined to be correct?

That's seems like a rather large amount of L to have to correct for regarding the observed current thru Rshunt at 1.5MHz.

So, what was decided, is 110nHy the value to use?

Well, it was measured on their inductance meter, a reasonably good one, better than mine for sure. I thought it was implausible for a while but that was because I was being misled by my meter, which doesn't like resistive inductors at all.

Several people suggested to her the correct way to construct a very low inductance CVR back in the day, Cheeseburger/humbugger for example, even including part numbers and construction drawings. Other people have used low inductance CVRs in there, and so did I when I switched to a single 0.2 ohm commercial CVR in Tar Baby, but not nearly as low as the ones Fuzzy has used or that Cheeseburger had suggested.
I used that value for my spreadsheet calculations when I was still using the 4, 1R sand resistors like she was using, IIRC, among other values as well.
It's a convenient value, though, because, as I recall, at the Ainslie operating frequencies the CVR's total impedance actually came out fairly close to 1 Ohm, if I did the math right, and so one could use the voltage drop in volts directly as the current reading in Amps.

TK,

If you caught my earlier post regarding the Rshunt L in the NERD circuit, was it decided that 110nHy was the value to use? (as stated in the "paper")

If so, when reading current off the 'scope, Rshunt would be closer to .96 to 1R at the osc fundamental.  I am trying to find a capture demonstrating 10amps of AC current as she apparently claims. 

I can't find a capture showing 10amps even if .25R is used as Rshunt (AC or DC).

xposting again I see...

Her builder has already told her that this present circuit isn't worth looking at, only the earlier Quantum circuit is of any significance, he believes. And he's sure that he's going to use driver chips for his mosfet..... and I am laughing, ho ho ho.

Not actually. It's a subject under discussion.  Here's the link...

It appears that she is not the only one over there that has no idea how the common gate configured Q2 operates in her circuit.

No mention of bias, linear operation, or negative voltage on the source of Q2 to bias it on.

And, apparently G has yet to look at FIG3 and FIG7 and realize that something is amiss with Q1. +12 volts to its gate and no current flow?  How can that be?  Is Q1 faulty, disconnected, or not connected as per the schematic?

He apparently does understand the common source configuration, so maybe he will see it sooner or later.
