I cannot read these ads for these transformers at this point and understand them. I know I need an audio and not power and I want it to hit 20k. I don't know if this correlates to audio frequencies and these are electrical... or if I am misreading? If anyone wants to point to a part on the parts express site for a torroid and say buy this.. go for it..

I am not trying to be cheap... I am trying to not overbuy. A difference. I want to build a few of these.

If someone could give me a few links (price range)to a few torroid transformers on the parts express site and explain to me what you are looking at and why this is priced higher etc... etc.. it would help alot. The power supply I am just buying constructed and variable and .5 ma 5-6k at the highest. Buying one for now.

edit.... I think those on the parts express site are all power transformers.. am I right?

Very Cool !!!
How thick is your coating?
I can't stress enough how importatnt it is test it before you start to assemble the panels.
I am very interested in how they turn out using the stator material that you are using.
I see that it is lincan type and I have been thinking about using it as well to build my smaller panels to compare to my window screen method.

Cheers !!

I have not tested the coating. I believe I have some kind of electrical measuring device but don't know exactly what it is measuring for...

I am using Spray On electricians marking spray 2500 dialectic multiple coatings. The stator material of the lincan type is only usable in a curved method unless it was braced with plastic or something I think which your windows screen method uses I believe. Even with the curve you cannot press to hard and must handle carefully.

It has taken me a lot more than just a few coats to even get to 3kv with out arc through.
More like a few cans !!!

You can do a simple test by using the bias supply that you are going to use and if you get no arc through using it you should have an adequate thickness of the coating.

I check the thickness of the coating with the use of a micrometer.

I have seen many go through all of the hassle of putting their panels together only to have to redo them because they were profusely arcing.
