Where to buy power transformer toroids?

May 07, 2010 4 Replies

I'm wondering if anyone knows an online source in the U.S. where a hobbyist could buy silicon steel toroids in small quantities, suitable for winding small off-line power transformers? The power rating of the finished transformer would be something like 50VA. TIA!

** So YOU are well able to wind 1800 turns of enamelled Cu wire for the primary - in and out of the centre hole - by hand no problem - right ??

Plus many layers of polyester wrap insulation and make it all taught and vibration free.

Then add a secondary of a few more hundred turns and get that right too.

Why not let a winding machine do it for you for almost nothing ??

Lemme guess - you are stupid ?

has the primary, only need to add secondaries, but unless he needs a really strange configuration of voltages why bother ...

Thanks, that transformer kit looks like it will do nicely!

I was looking at the manual for the Tek TM506 yesterday (a rack for various plugins). The mains power transformer has 16 secondaries! :)
