Nick,

thanks, you are right, mazilli it is.

I am collecting the parts to build this latest design (on a breadboard first), thats why i wanted to know what was being written there.


Regards Itsu

Itsu,

You probably know this, but the switched-mode transformer specified as ERL-35C can be found as the main step-down unit in a PC PSU. The one I tested has a step-down ratio of around 5:1, so can be reversed in operation for step-up working. Although type numbers vary, most can be pressed into use for this application by selecting and measuring and FG scoping for suitable windings.  You should get a nice angry spark at the output with this setup! 

I would guess that the 330 should be 330nF rather than pF, as its at the input of the logic gate feeding a comparator (pin 3) from the VCO output (pin 4). So, I think the cap and pot are used for signal conditioning.

Yes, it is a low pass filter. F=1/2*pi*R*C

Hi
so I guess that it 330pF so this brown to ground in the upper left corner of potentiometers, which applications have chosen to build this PCB with SMD chips?  keeping track of your new project and I'm curious how you deal with synchronization thanks for refresh.

Here you can see a little better but it is 22nF

The Russian standard capacitance values without marking means lowest range.
So 330 = 330pF, 33n = 33nF and so on...
