Questions Meyers VIC circuit?

[slider1]

Two questions.
Meyer has different versions it seems of his vic. One on page 22 of his independent test evaluation. This looks like it is a variable power supply 0-120 v rectified. I see how he gets his pulse train but he always talks about high voltage. I don't see that here? Am I missing something? I see in some places he talks about voltage in the KV range and frequency in the kHz range but this is 60hz.

Second if you have a bifilar coil for a charging choke how do you have one adjustable without affecting the other?

Here are some links that may help you understand how to increase voltage like a step-up transformer, but, without one.

As far as I know, to have one variable choke, the two chokes would either have to be separated or taps could be wired in if they are wound together. In my opinion, Stan added the tunable choke for obscurity. None of his working demonstrations had any visible tunable choke.

The HV is achieved by charging the watercap with lower voltage pulses.

The tunable choke is in the original patent.  I think I've seen one picture of what I thought was a tunable coil, it looked like it had a brass wiper attached, like a crystal radio coil.  I think it was in the D14 document.  As I understand, it wasn't until later that Meyer suggested the differential mode bifilar choke.  A further revision with all windings on one ferrite can be seen in the WO 92/07861 patent Figure 1 ( http://www.rexresearch.com/meyerhy/wo92.htm ).

In that picture, TX1 is a primary of a step-up transformer.  The TX2 secondary has many more windings than TX1, so the voltage is much higher.  TX4 and TX5 are the choke coils, notice there is no tunable feature shown in this drawing.  TX1 and TX3 are in the pulse generator circuit, the rest of the coils are isolated and connected with the water cell.

I'm personally interested in TX3, which is a feedback to a phase-lock-loop circuit.  When the cell goes into resonance, that coil sends back pulses... at least that's how I understand it.  I'm trying to get there to find out 

I can't quite figure out what you mean by the rectified 120V 60Hz thing, the Dave Lawton style dual-555 timer pulse circuit is what most people are using to drive a resonant water cell with wind-chime style electrodes.  I think you may be confusing this with the Boyce circuit, which is a combination brute force and rich harmonics circuit using flat plates.

I've read one document that suggested using an old neon sign transformer for the VIC.  A new 120VAC to 6000 volt coil is around $50, but you may have to remove active components that they mold into the unit.  Driven with a 12 volt pulse, you should get several hundred volts out of the secondary, so be careful, it won't just sting... it can KILL you.  A standard transformer that converts US 120VAC or european 240VAC to 12VAC can also be used hooked up backwards.

The question was about this circuit which was used in his independent study. This is the original VIC before any improvements that was publicly demonstrated along with the rotary version. It's just plain jane but it's what he used to prove his work. Notice the 0-110V variable transformer? AC 60hz rectified would turn into 120hz DC pulses.
