Dally have made another Solid-State-OU-Generator.
Does version 2 work as well as version 1?

Further to my post 224, the KD226G diode is not packaged to take a heat sink.

Hi guys!

Posted photos of "green transformers". This is what I found in my pantry. This is a military standard for special transformers, of which there are a huge number of specifications. Produced on the U-shaped cores and toroids. I disassembled the transformer, such as the Dally.
The core is made of an alloy of "alsifer" (aluminium, silicon, iron) or mu - permalloy to avoid saturation. Cores are designed to operate at low frequencies up to 10 kHz, where the use of ferrites impossible.
Dally just picked suitable transformer for his DC-DC converter.
To make such a transformer  I can recommend the rings
made out of u-permalloy.

Regards
Vasiliy

You may use bigger ring up to 2 cm outer diameter.  Ðœ6000НМ or better.

I do not agree with Sergei, this fundamental error which began to make in our forums. In this scheme, the core must  to work in saturation mode, otherwise the effect DSRDs diode is not going to happen.
It is necessary to use small-diameter ring, as shown in basic scheme, it is 7 mm outer diameter.
In the scheme, sloping line indicates on the  transformer in  saturation mode.
The larger the size of the ring, the more difficult to enter it into saturation.

Ferrite is going hot so must be sealed or glued on KT926 radiator.
Yes, the ring will heat up, it will need to be glued on the radiator.

Excellent thanks. Now we have last bit of the jigsaw.

I agree. The transformer method of driving the DSRD requires the saturation of the ferrite core in order to create asymmetrical currents in the forward and reverse conduction of the DSR diodes.
I think that tunning the saturation point of this transformer is tricky.  That is why I prefer the transformerless method of driving the DSR diodes.

You need not reinvent the bike. This scheme works quite good without complicated settings. The scheme was worked out in the Institute of Nuclear Physics, Academy of Sciences of the USSR. The document is in Russian, sorry. If necessary, can translate the most interesting moments.

IMO its important that we replicate as closely as possible to Dally's schematic before any alternatives are tried.

That's my point!  A saturable transformer is difficult to match. 
Its ferrimagnetic core has many parameters that need to be carefully tuned (e.g. dimensions, the AL value, BH characteristic - saturation point, permeability, frequency response).
You cannot just write: "use a 3cm OD ferrite torroid with 12 turns of wire" and expect it to work as advertised just because it worked for you or someone else.
The results are unpredictable unless you use the same core.

@Hoppy
I agree, but do you know where to obtain exactly the same core as Dally's?

Totally agree with you. How to build is a personal matter. If I offended you, I'm sorry.

Good point and not easy to match. I have a 10mm dia ferrite with the same other dimensions but this was recovered from scrap equipment so i don't know the source. I'm going for a suck-it -and- see approach with this one. I'm hoping that we may at least see some interesting reaction even if this components dimensions are critical, which I doubt.

By the way, I do not know how you do, I usually measure the permeability of unknown rings by the formula where is shown in the photo. May be useful.
Necessary to make the winding of 5 turns, any suitable wire. Coil placed evenly around the ring. It remains only measure the inductance of the coil and substitute the values ​​into the formula.

Does the КР1533ЛА3 Quad NAND Gate  belong to the 74ALS... family?
Why is it necessary to mix different logic families? AC and ALS ?


I have found that the 74HCT00N will not work in the VCO but the SN7400N or SN74LS00N will. Either will work in the nano pulser.

That's a good formula if you know the dimensions and inductance L.
From my experience, L at 10kHz is very different than L at 10MHz.  I don't even try to measure at GHz...

P.S.
You have not offended me. Don't hesitate to disagree with me, if you think that I am wrong.

I managed to power up the completed device without the AT PSU before I'm away from the bench. Nothing special was observed during tuning with various caps across L2 and adjustment of VCO and no rise in output voltage on any winding. I'm not happy about the nano interface to the co-ax driver transistor as distortion of the pulse is visible at the collector. The nano with output disconnected produces clean sharp pulses. A ground earth was also applied as per schematic.
