@all

Here we go again. I mention possible button battery in the those v3 pots and all hell breaks loose. Yes it is possible. Any OUers with a responsible mind would consider that especially when the AK30 has two encased pots producing 30 watts and the v3 producing a few watts has 4 encased pots.

It is also possible that two of those pots are used in series if they are used to adjust in the 1 ohm capacity so they may not have button batteries hidden in them. We don't know but there is no point trying to overly delve into it. It was just a responsible comment.

@TK

Over at OUR in my last post I asked several questions regarding the official AK30 schematic. Not one answer or comment on those points and I will not move forward if they are not considered.

Basically we need a qualified EEer to look over the circuit and mostly the resistor, cap and pot values around the main IC and confirm that those values are within the acceptable levels for this IC to function at its peak frequency range.

You see, we get inconsistent information all the time. @T-1000 just posted that the resonance has to reach the cores resonance (simply put) to have some "nuclear" effect. But how the hell do you except to achieve anything of that level if your circuit is locked at 300KHz. Something is wrong with the values.

My preliminary tests show no resonance worth considering below 300KHz, with very high peak resonances in the 490KHZ - 1.2MHz range. Then we have the fact that the official photo of the circuit board does not match the diagram. The diagram shows three mosfets, the board shows two including a JFET type that is not even mentioned on the diagram. The actual ecore has three coils where the circuit only shows two, etc, etc.

So if you or any other qualified person can take a forensic look at the circuit, values, IC pdf, etc and ascertain their appropriateness this would be of great assistance to all. Particular concern is off pins 5 and 6. Seems to me pin 5 should be a 1n and pin 6 should total 500k but all would have to be confirmed in case Akula decided to change the real values before he published the schematic.

Then it will be to reconcile the fact that the Ecore has three coils with a total of 5 wire connections, not 4. That will be another point to figure out.

@all2

There's other sleuthing that still needs to be done. Someone with good visual component ID skills needs to look at the AK30 circuit photo and match all possible components on the board photo to the same schematic in order to identify which components on the board diverge from the schematic.

Hey BR549,

Good Question. The look pretty good to me. See attached Pics.

All the Best

Chris:
I think your right. The lighting is a little different, but I think they also; both look the same.
I am currently building the Akula device that uses the MC34063A/E, but have been looking at
this one. (Depends on how the first on works out).
thank you;  br549

T-1000:
"In this case the LC resonance frequency must match ferrite natural resonance frequency or its harmonics."

for example: if you have yours transformers ferrite resonance 2.23 Mhz, you could reach the core resonance excitation with coils resonance on 22.3 Khz or 223 Khz

Uses two TL494, right?
You could try it?
