Default PCBs

I'm looking to build a couple of amplifiers based on the TDA2009, or other amplifier that will operate at 15vdc, and put out 5-10w stereo into 4ohms.

Also, I would like to have the second one bridged, however, is there a source for PCBs or reference boards for these? I see mock up boards on the data sheet for the 2009, but can not find a source for them.

Thanks!

How in the world do you possibly do that? This is my first project and I feel way over my head!, but I don't have the money for a commerically done project, so here I am ;P

Is there anyway of making a project without a PCB, and would involve, a lot of wiring, I guess?

My plan currently is to make 4 TDA2050 amplifiers on a 6"x6" board, is this possible using standard breadboard, or what should I be looking into, given that price is the biggest concern, however, there is no sense on saving money if the final product will not work

Default You are not alone!

Etching PCB:s

And it is not to hard! If you want to go without the PCB you can make the whole amp on perf board. It's bare PCB with holes drilled every 0.10 inch.
