The only differenze Is a little roll off from 40hz on mine.
The real unit Is flat from 0 hz.
Insider custom fransformers

Nice thanks for your reply.
How much did it cost you for one clone?
Would you please share the schematics and explain me briefly how to build it?
Thanks so much for sharing this.

The cost was near 1600 euros for unit.
I don't have a schematic.
Time ago my friend take me the real unit for 6 months.
I've reverse engeniering and measured all parts.
I've rebuilt the same bord on sprint layout software and send them for printing...
