Anyway Guys,

I've completed a marathon of my own since 2.00 am this morning.  Right now I intend enjoying a pleasant evening with some pleasant people.

TK - at the risk of lapsing into the vernacular - 'DO YOUR DAMNEDEST'.  To picowatt - INTERESTING to see that you're qualifying those reckless claims of yours.  Magsy - sorry to see you're so easily DUPED.  To Sean - I'll deal with your email either later tonight - or tomorrow.  And to our readers - I suspect this has been reasonably entertaining.  But just wait for our 'live screening'.  That'll keep you RIVETED.  And poor little TK will implode with all that pent up malice.  I've got a sneaking suspicion that they're all rather anxious to deny our claims. 

LOL

Kindest regards,
Rosie

They are very far from reckless claims.  And my only "qualification" is that the 'scope be used properly.

@Picowatt: You asked about Groundloop's H-bridge circuit. There have been several; some years ago he and Gotoluc and I were playing with some of his circuits and effects produced by resonating coil/cap arrangements. The one used in my "resonance effects for everyone" videos on YT is a proper mosfet H-bridge using actual mosfet driver chips and works very well at usable frequencies (tabletop sized 1/4 wave resonators). I don't have that unit available to me right now, it's at the other undisclosed location, unfortunately. The schematic for that one is on an ancient thread here somewhere; perhaps Groundloop is reading and remembers it and will post it; I don't have it in this computer at all.

The H-bridge circuit that blew the Darlington so spectacularly a couple days ago is something different... and I can't really recall who sent it to me. It could have been Groundloop or Gotoluc or another person with whom I was corresponding at that time. I am really sorry, I apologise for not recalling the person who was so kind as to send me the printed circuit board and a pre-programmed PIC for it. This one is optoisolated, driving the Darlingtons directly from the opto outputs, and uses the plc and a crystal oscillator for pulse shape control, and is clocked by an external FG input. I finally got around to building it up. I delayed for so long because the specified Darlingtons are the pricey MJH11022. But now I've just built it to play around with using TIP122s. I also don't have the schematic for this one, but the output side is dead simple: just pulldown resistors and the direct output from the optoisolators driving the Darlington H-Bridge, no caps or inductors, and it tops out at a couple hundred kHz... too slow for small TC use unfortunately.

I wish I could remember who sent this to me, I've learned a lot from it and I'd like to thank them again for sending it along. If it was GL, Thanks! And if it was someone else... please let me know, and forgive me for being so tardy in building up the board. I've moved locations several times since it was sent to me...

And finally, the Class E sstc that I'm tuning uses a single mosfet as an RF amplifier and is more similar to Ainslie's circuit than to anything else -- even in its use of feedback oscillations. Just as when I was working with the COP>17 circuit, I find that it's better and more interesting to switch mosfets PROPERLY and use them to make really INTERESTING effects. I started developing the TinselKoil circuitry and resonator when I got bored with Ainslie's BS the last time.

There is no way that while using the same DC coupled 'scope settings and identical gate drive waveforms, that a functioning Q1 can be connected as per the schematic and not show significant current flow via the CSR.  Can't be done.  No one can do it.  Not possible.  You should be considering how you are going to deal with this very real issue, instead of arguing that it does not exist.

Applying +12 volts to the gate of Q1 MUST turn it on unless Q1 is defective or not connected as per your schematic.

So keep up with the insults, your skills at doing so are way better than mine, you are indeed an expert at that.

But, it will not change the facts in evidence.

I have been suspecting for some time that we are not being told the truth about the actual schematic used for some of the trials. Certainly there have been many versions CLAIMED to be used, and certainly Ainslie has lied about and covered up changes and errors in the schematic used before this. Her continued smugness about mosfet heating and about this current issue might possibly be explained by the use of a different schematic than the one we are being told was used.

Recall that in the "original" version of the manuscripts, there was a subtle but highly significant difference between the two schematics given.

Also you will recall that there was a considerable degree of prevarication around the VIDEO DEMO, which claimed to use one schematic, attempted to use another, and actually used a third one, and then was claimed to use a fourth one. 1: single mosfet diagram shown. 2: 5 in parallel was attempted. 3. The miswiring mistake... but FG connected to common ground. 4. The representation of the experiment with the FG on the transistor side of the CVR instead of common ground.

At this point there is absolutely no telling what Ainslie is hiding and I have long suspected that she is concealing the true schematic used for some of the tests.

TK,

I never was much of a fan regarding Darlingtons, particularly at HF.  Many of them tend to be a bit slow turning off.

You have some really cool stuff there!

Have you attempted to look at the gate drive whle the circuit is in operation?  Are you showing a consistently clamped gate drive signal?
