Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I guess I should try to get 3 x 3kw toroids, and maybe a 1.5kw with the reasoning:

2x toroids for the large transformer
1x toroid for the medium transformer
1x 1.5kw toroid for the small transformer
1x something else cobbled together for the tiny transformer

sound like a plan?


Both Klaus and Mark have done exactly that, and it worked out very well both times.

I have contacted my mate Paul V. and see if I can get a quotation for winding transformers similar to my own. But I fear that is going to be a very expensive option.
Cheers,  Tony.

Thanks for the heads up! I bought it. It's not quite the power I will need ultimately but it's a great start.

I bet it won't come because it's too cheap to be true. $22 and $100 shipping to Australia is just too cheap to be true. I'll get my money back via PayPal if/when it doesn't show.

The two pics are the same Transformer

It has been listed at least 3 times

The price gets lower and lower until it ends

That price includes shipping in usa

It is out of a powerjack

Do your own research but I think this last pic has a toroid in it also

I am prity sure the Transformer you already bought is the exact same one as the one on top in this pic

The one in pic has first winding off already

If you can't find another one to stack with the one you bought if that is your plan let me know
