new one pulse transformer :
OD = 14 mm
ID = 7 mm
TH = 3 mm
W1 = 3 turns = 24.95 uH
W2 = 10 turns = 236.3 uH

OK, I updated the table above with this new data

Had anybody have the opportunity to analyze this post?

I just read the following in the machine-translated Belkin paper , regarding the driver circuit attached below:
1) It is a DSR Diode driver after all
2) Its maximum pulse repetition rate is 5kHz
3) The Tr1 heats up and should be placed on the radiator
4) The Tr1 should saturate when the voltage across the capacitor is at its maximum and the current in W2 is at zero.
5) The dots denoting the beginning of the Tr1's windings are correct and the forward conduction of the diode coincides with the positive pulse on the base of KT926 transistor.

This is the same circuit that Dally is using.

4) The Tr1 should saturate when the voltage across the capacitor is at its maximum and the current in W2 is at zero.

So the saturation of the core is caused by current through W1

5) The dots denoting the beginning of the Tr1's windings are correct and the forward conduction of the diode coincides with the positive pulse on the base of KT926 transistor.

Normally the dots denotes the same phase relation in a transformer, so with a FG and a scope i should be able to find the same phase relation on W1 and W2 and connect the DSRD and cap correctly.

Great info,  thanks.

Yes

Normally the dots denotes the same phase relation in a transformer

For the Russians "Normally" means that an "open switch" has zero resistance and a dot marks the end of a winding.

Attached please find a slightly improved translation of the Belkin paper about nanosecond pulse formers, that were used by Dally.

Fig.22 illustrates the circuit that Dally used to generate his nanopulses and Fig.1a and its associated text, explains the operating principle of this nanopulse generator based on a saturable transformer.
