Cheap AC flybacks

[Alberto]

Hi everyone.

In other post MRMILSTAR suggest sanyo F0239 as a AC flyback. The model F041 is AC too. The question is, looking up in the internet, I have found a USA online shop that sells them.

Less than 17$ each.

But which does it gives more voltage? Maybe I´ll buy the 2 models, but It woulf be better if I had more infromation. I have looked up but I have found nothing.

Thank you.

Kind regards

Be careful.  These AC flybacks (F0239 and F0241) keep showing up cheap on scam web sites.  Cicon does show a physical address and history, but a quick search also shows complaints about never receiving parts that were ordered.  If you do successfully purchase from Cicon, please post that.  The price is good if real.

Thank you for the advice!!

Ok if I bouhgt them I´ll tell.

Edited. Yes, there is a huge amount of complaints in the internet. I don´t think I´ll buy there.

The problem whit these flybacks in ebay is shippings to spains it cost more than the flyback

Hi everyone 

I found some cheap AC flybacks on aliexpress : https://m.aliexpress.com/item/4001091321165.html
they were featured in a video (

)
they must be used in oil / wax to avoid corona discharge

Yes, I have this one, but is a little bit small. I don´t know if its performance is similar to the regular AC flybacks like F0239 or F0241

Here's one data point. I use 2 of the F0239 flybacks in parallel to drive my 14-stage CW voltage multiplier. They are drawing about 240 watts combined with a ZVS driver, so they can supply decent power. The current HV power supply voltage is about 10 KV RMS AC. Here is a picture of the HV power supply.
