Default Help with powering an amp!

Hey everyone, as you can tell i need help. I'm new to the whole electronics/audio thing. I have a velleman K4003 that i built and need help with what i need to power it. I kinda have an idea of what i need but someone specifically telling me would be great.

Here's an address to the kit. Velleman, Inc. Thanks

OK so the kit asks for "supply voltage: 2 x 12V AC / 2A (50W transfo recommended)"

When you rectify this (Convert AC into DC) you will end up with around 16.8volts.
Multiply the transformers AC voltage times 1.4 if you ever need an approximate DC (Rectified) voltage.

Here is a link to a suitable transformer. Antek - AN-0512
A "regular" transformer is fine too, I just linked the "Toroidal" transformer above, because the price is reasonable and shows the dimensions etc.

Here is a link for a regular transformer, normally these are less money then a Toroidal, but AnTek has some pretty good prices.

A Toroidal is considered to be an "upgrade" from a regular transformers. That being said a normal one will do you fine.

Make sure you check back before you plug it in, someone here can show you how to make and use a Bulb Tester.
