I know currunt flows around the wire and not thru it, so to me, that cheaper coil may be more efficient. But the load would be compramised, i believe there would be more resistance using the cheaper coil. just some thoughts. __________________ The only true wisdom is in knowing you know nothing.

Regardless I will get either the 25v or 6v 50va. Always remember regarding math and electronics I never know what the help I am talking about. Merely typing and ordering...
 28th November 2011, 08:23 AM #63 SM7UYJ   diyAudio Member     Join Date: Dec 2004 Location: Staffanstorp With 25V sec. you get 230/25 = 9.2, using two toroids you get a teoretical transformation ratio 1:18 - unfortunatly way to low! With a 6V trafo you would get 230/6 = 38.3, two toroids => 1:76 So using the 25V version trafo, you will need 8 toroids to get abt. the same transformation ratio as using two 6V! /Roger __________________ The probability of someone watching you is proportional to the stupidity of your action. - A.

For hybrid ESL's, I recommend a pair of these trannys driving each panel:

 28th November 2011, 09:15 AM #65 Calvin   diyAudio Member     Join Date: Nov 2004 Location: close to Basel Hi, the theoretical U is N1/N2 or V1/V2, which gives 1:76 for a 6V/230V pair. Connected in parallel on the 6V-side and in series on the 230V-side. In praxis You need to include the efficiency of the tranny, which is typically around 90% in the required wattage-class. So the effective U would be 1/(76x0.9) ~ 1:68. jauu Calvin

I am going to have to dive into some electrical theory

just tell me what to do.

Going to order a variable low power high voltage supply prebuilt. Know enough to do that I believe on my own.

I think I need a high voltage multiplier... found those on ebay. Some resistors high voltage.... well do me a favor... I will stay at this thread and update it with what I bought or thinking about buying.

 28th November 2011, 09:59 AM #70 joojoo1234   diyAudio Member   Join Date: Oct 2011 Well I ordered 8 of those AN-0506 transformers. i have spare metal and family. As I am still learning I am forced to ask this question. If I use 3 of those per speaker would it be enough to drive a full range... say to 100-150 mhz if I should decide to do a design like that later?
