Hi guys, im trying to build the cheapest possible amplifier, at least 50 Watts and low THD

Can someone please tellme some amplifier with that specs?

Sorry but what spec?

You'll need to provide some definition of what you expect in terms of cost and performance or no one will have a clue what to recommend.

For instance, are you looking to build under $100, $200???

Is 0.1% THD good enough or do you expect better?

Initially, I would recommend a chip amp for most bang for your buck.

Hi,

If you want to build a discrete amp and do not want to spend too much, maybe you can read about the Mosfet Citation 12 by Nelson Pass or the project 3A from Elliott (few components, truly excellent sound, and he sells excellent pcb for the amp).

Pass Labs: Technical articles
60-80W Power Amplifier

As for cheaper chipamps, you could try with TDA7394 (Arg. Pesos 15 per device). Good sound overall. Very few components.

Good luck,
M.
 
Very good sound from fellow Argentinian designer

Build this and be surprised of it's performance. Output can be any type you can get hold off.
