Marco, I understand the picture now I thought it was something else.

let this be know en

in me posting this i got a very bad head ache ........ almost instantally


newton do tell me where that came from.......


isteam!!

i will not be controlled thank you!!!!   i will be screaming freedom in the streets where the peoples meet!!

in case he doesn't need it, I DO!!

feel some noise comming up again...

Always best to ignore the background noise if you can't get rid of it.

Hi Grumpy,

I got your "message". I am still new here.

Wow, you found some fly back transformers.
The wave form comes from the horizontal control circuit, then that wave form signal @ (14,000 > HZ) is fed to the grid of the horizontal output tube the big one if you have the set..
The transformer does not shape the wave form.
The power from the horizontal output tube powers the fly back transformer.
This is done at about 600 volts off the plate of the output tube. It would be hard to operate without the rest of the circuit and the schematic.
There is a damper tube also to control the fly back transformer.
It all works together as a unit.

If you do try to try to power it up with some square wave generator amp set up, watch the high voltage! about 16K!!! RF before the HV rectifier.

I am doing this from memory (1968) so don't quote me on this information. But do be carefull. It will jump out at you!
Do you see the design?

Remember, this is where the inventor's head was at, at some point before he invented his device.

I want to say, 14,000 something HZ, but not sure,
However it is a industry standard and all US made sets used this same exact horizontal sweep frequency.
In the same exact wave form. Spike with a slope. The vertical output was at 60 HZ., so this was no good for HV generation for the CRT.

But the AC line power was used to synchronize the 60 HZ vertical sweep. So if you had trash on the power lines, your set would go whacko.

The transformer is designed for just one frequency sort of like the TPU except the fly back transformer had to be dead on frequency or the set would get those strange horizontal lines.
See the one loop HV rectifier heater winding?
See the insulation?
It was at high voltage potential too.

Then the horizontal oscillator tubes would get weak the frequency would drift and the set would go out of kilter, even though you still had a picture of sorts.

However there hundreds of different designs to do the same thing usually in a effort to save costs so as time went on they, after about 1971 turned to crap TVs, not even worth repairing, the BW ones any way.

The fly back has a special iron core, design, the TPU has a air core, ahhh something?

The TPU has to be off to one side of the frequency or according to the inventor. Boom!

more winding...
