Thank you for your excellent work in tracing the circuit. You may be interested in what I wrote in this thread:

If you can check your board against the attached schematic it would be helpful, as I believe this schematic is the correct one. You can see the erase marks where the corrections were made, when comparing it to the original 1st version hand drawn schematic. The other cleaned up schematics have at least 3 serious errors.

BTW, things are getting quite confused with all the Akula versions. Perhaps the administrator could start a thread called "Akula Dual TL494 Device" and move all the appropriate stuff there.

The scope troubleshooting stuff should also go elsewhere, as it is a derail.

Thnx Vortex!

I have opened a new thread for the dual tl494
http://www.overunity.com/14610/akula0083-light-no3-dual-tl494/new/#new

There we can play with the dual TL494

I also signed up at realstrannik.ru to see if i can provoke Akula himself :p

That hand drawing from Abtop, is wrong it has a mosfet driver by the first mosfet, that is the circuit for the one with that step down thing from the first movie, it is not the same.

@All,

Yes I believe this is right, the schematic mentioned above, which we have been referencing as 'Grandfather Scheme 2' which was the original name of the schematic when posted here, is of the Akula0083 Lantern No#3 revision 1. It appears to be the next version after the one with the external Switch Mode Power Supply.

All the Best

@All,

I would like to propose the possibility of the Lantern No#3 circuit working as an over complicated H-Bridge or correctly, a Half H-Bridge.

If the Coil that was actually the input coil was in fact being driven with a series Resonant LC Tank via an overly complicated H-Bridge, or correctly, a Half H-Bridge then this may explain the fact that the 9 Volt Battery (only capable of providing a few milliamps) could have started the device.

A Dual TL494 Half H-Bridge circuit is provided below for comparison.

Maybe we are looking at this all wrong.

All the Best
