hello again - does anyone have rough estimate of a reasonable cost for litz wire? 90 ft will cost me about $15 Australian dollars. multiply that by 4 and you have $60 worth of wire for just one transformer...does that seem correct?

No, that is ridiculously expensive. Find a different supplier.

Some time ago i asked for a quote for Litz wire. In small quantities it came down to about €16 per transformer.

That was the company i asked. They connected me to the Belgian dealer who quoted me this price for a small quantity. How much did you pay?

The price was 45eur per kg!

Hi Anthon!!!

Yes winding your own trannies saves the money a lot....

It is built from scratch and CJ recipe!!! ALL THANKS TO CJ!!!

Here is link where recipe can be found.

https://vacuumbrain.uk
And this trannie is very simple to make!

It is quadrifilar type of trannie!!!

Do you have another link to the recipe? Looks like that link doesn't go anywhere - very interested in winding some Litz 2503's.
