change 15K to 5K as in schematic on first post. LTspice results: V+ 12V V- 2V and split rail at 7V. So 5V either side of virtual ground. Seems good. Sacho schematic appears to be correct or am I missing something.

[dbanner]

the circuit comprising (Q1,Q2,Q3) VT6,VT7and VT9 I cannot give a reason for it.

What you are trying to achieve ?

[dbanner]

I noticed error a transistor VT9 is connected back. Please for excuse.[ATTACH]46087[/ATTACH]

yes

This is how it was meant to be, I think. Now I can make out it is a pass transistor. Circuits are easier to follow when drawn properly.

...Circuits are easier to follow when drawn properly.

Exactly!
That's exactly what I wrote at least 50 times in the past 20 years!
I don't want anyone to misunderstand me.
But Sacho is full of schematics and has published quite a few so far.
He made arrogant bold statements with each one.
But until now, in the last 20 years, I personally, unfortunately, have not seen ONE video showing that any of his schematics actually work and are even worth something.
Once upon a time, naively, I tried to make a couple of these things.
Nothing ever worked!
Of course, if you dare to write such a thing publicly on the forum; immediately he appears, full of anger, ready to argue and always gives the reason "your ignorance and incompetence are to blame for it".
That is why all that he has published so far; I threw in the trash and I've been trying to totally ignore such trash for a long time.
I wouldn't comment anything here now, but you pulled me to just confirm that great truth.
A terribly poorly drawn schematic that looks like it was deliberately and consciously complicated by the most nebulous way of drawing; probably seems "advanced" and "profane" to some retarded mind.
But when you redraw it in a good way, then you can clearly see that it is a rather rudimentary and extremely backward project.
Which has very little chance of ever working very well.
If I were you, I would give up on that nebula and turn to projects that have already been confirmed on the forum by many members who have already done it.
This is just a waste of time.

Even better rendition. Perhaps this is how a well drawn schematic is supposed to look. However, I'd much prefer a poorly drawn circuit that works, rather than a well drawn circuit that goes up in smoke.

[ivconic]

I always prefer ONLY well drawn schematic that works!

An example of a schematic I'm working on. It's a redraw of the AF108 but without the frills. I'm playing around with sPlan 7.0 , getting used to it. I kinda like it.

Sacho's schematics remind me of the The Voynich Manuscript, for some strange reason it comes to mind.

Hi Dbanner,

have you notice that the AF-108 circuit is almost the same as the Whites PI1000?

[aft_72005]

About sascho schematics .... I built sascho VLF nexus many years ago ... worked well

As I know many people built Sascho 2 box in Iran ..also working well .

but Sascho SBG pi .. power section had ERORR in drawing

where is transmitter ? seem not completed

[aft_72005]

i am interest seeing all schematics' published by Sascho .

please upload
