Hey Usman

1uF would work fine, but watch the temperature of the capacitor.

Its a MKP not MKV capacitor, its short in Europe for metallized polypropylene capacitors

Kind regards

I went through my stash of capacitors and found a 2500 volt, 1 micro-farad capacitor. Would that work just as well?

Does anyone know any replacements for MKV capacitors? I can’t find them anywhere…
I am currently using newark to purchase my parts, “http://canada.newark.com”.
Thank-you!

Hey Alex

Good results you got there

Keep experimenting!

Kind regards

I finally got round to trying mine out on 36v input,

lol I originally had the same problem as you did on that photocopier flyback, my primary coil wire was too thin and started smoking!

No you can not, if you look at the datasheets for the 2N3055 transistor and the IRFP250 MOSFET you will see that there are considerably differences in their specifications and they are not even the same type of transistor.

can is use the 2N3055 instead of IRF250at same 20vDC please reply me i am about to do this because this circuits gives good performance rather than other circuit i am waiting for your reply…….

Thanks for the reply. I will leave the revenue sharing for that video turned off then, or at-least until if the video ever became very popular (which I doubt it ever will).

Oh I know that it was designed by Vladimiro Mazzilli and I have given him credit in the description. (Any idea what year he came up with it?).

Regards,
Alex.

Hi Alex

Its is infact Vladimiro Mazilli that deserves all the thanks for this design, just a heads up on ads, it takes years to get a payment when you are just a private person

Kind regards

Hi Mads.

YouTube have recently gave me monetisation features which enables me to make money from adverts on my videos.

I have enabled them on a few of my videos already but though I would get your permission first before I enable them on the video I have embedded in my comment above. Since I followed your component list in the schematic to make this circuit I feel I should ask first before I enable adverts since you came up with what components to use.

Just let me know in the comments here, I will not be offended in any way if you do not want me to enable adverts on the video I uploaded above.

Thanks,

Alex.
