Default Transformer Making

Dear Friend,

I am going to make a transformer (step down/9-0-9 volt/3 amp current) for my audio amplifier. I want to know everything about transformer making ( types of core,bobbin number,copper wire thickness,etc.). Can you tell me the urls about it ?

Thank you,

Have a good day !

Why make and suffer three iterations to get the correct voltage/ better purchase it from off shelf. perhaps it may work out cheaper.

I agree, for such a common and low power transformer it should be easy to pick one up from surplus and E-bay type sellers. Now if you were talking about 2KW transformers then that would be another story.

Sorry but I don't have any decent links for transformer construction. It is a pretty specialized field and takes plenty of tricks and experiance to get them right.

Good luck

Lefty
