Hi all,

I've decided on a very simple circuit to make a power supply whilst I wait for a better one to appear on Ebay.

However, I'm having real problem tracking down a 20VA 9V-0V-9V transformer. Reading this datasheet;

http://www.rapidonline.com/netalogue/specs/88-3416.pdf (Page 1of3)

It says that these transformers can be wired to centre tap.

How would I go about doing that?

Thanks,

Sparky

 

The two secondary windings are labelled 0 V 0 V.
Connect the two middle tabs V 0 and use that as the centre tap.

QFT. I agree.

 

Hello,

I have taken the transformer drawing from the datasheet and made the connections in it.
The Mains connection is made for 230 Volts now.

Thanks guys, I really appreciate your time and help.
