Peter,
Lol, you should rustle up a homebrew curry for your better half to keep her sweet, plenty of onions fried in plenty of butter until caramalised and then just bung stuff in (meat, veg etc) with curry powder and Yoghurt and coconut powder for a korma, tomato puree for baltis masalas etc.

I will remain positive, it's the only way to proceed as you say.

Maybe a NST is OU at resonance if the input is set up as a tuned tank thats pumped at secondary resonance? easy enough to test with HV diode bridge and cap bank on the output, hmmm.

Speaking of testing, one thing I really need to get hold of is a variety of purely resistive shunts like say 0.1, 1 and 10 Ohm. At RF wirewounds are too inductive. I've read a saltbath and stainless electrodes makes a good zero inductance shunt but it's not practical and I don't want brine all over my bench and equipment.

p.s.
can you recommend any uk seller for castellated Grommet Strip that would sell a meter or two?

Lol good idea with the curry

The Grommet strip i bought was £5 for 5 meters, i cant remember which size i used now, but can tell you when i get to work tomorrow they do 2 different sizes.

I have used all 5 meters on 2 40 turn coils

I wonder if it's possible to use carbon rods for resistors?
I once made a pencil lead glow nicely using a battery
maybe too high in ohms for 0.1 though

Saltbadh ? good idea, bat you never find 0,1 or 1 Ohm.

Use One Constantan , copper or simple steal/ion wire

fold then double or quart (4-times)

so you have not more inductance.
even if you wind them as an -small- bifilar tesla pancake coil

There are relatively cheap current sense resistors that are low inductance and not too expensive.

Farnell show 866 items for current sense resistor search although some are US stock

I have used this one before

here's a non inductive 100 Watt but it's £28

Check this out...

My little not so accurate hairpin lighting an led on dc and ac at the same time on the same coil.  It is also able to charge caps!!!  The coil is one of my JT's but I'm only using the single pickup.  Voltage on my DMM on the dc side is 2.63v.  You can notice the coil is on the wires from the gap...yes I know there is induction going on but the energy is coming from either side of the gap apparently like Ed Gray described and I can move it off and still light the leds they just aren't as bright.  Anyways some food for thought.

P.S. With 1 or 2 leds the voltage and amp draw is the same.

Ill let you know how far it will charge a cap when it's done.
