This thread is for Akula's Lantern v3  O0

I think we have more information on this device than any other Akula device.

Both chips are TL494.


I believe that the core is UR48/39/17-3C30 as it matches shape and size.  There is only one other Type 1 and too small.

Core type: Ferrite UR Core - Type 1 (UR48/39/17-3C30)
Core grade: 3C30
Gap: Yes (paper)

The schematic GIF is corrupt. [FIXED] I got it from over on OU.com  The only way I can view it correctly is via Firefox.  Can anyone open and save as a jpg?

Edit: TutorialFE was able to make a clean jpg of the schematic! O0  I have updated OP.

Here is a even cleaner version of the circuit.

Attached is my best "GUESS" to what components to use
in this circuit. This version removed the unknowns in the
first posted circuit.
