I know this probably sounds very lame but I have no idea where to start as I embark on this project. I searched for the word “beginner” in the forum but even what that turned up was a little too advanced for me. Please can anyone help me with at least a starting place to go from? All I’d like to start with is an amp to take a headphone output and power a pair of cheap speakers (Specs below).
Any help would be much appreciated.
Long Term Power 50w
Short Term Power 90w
Frequency Range 84Hz – 20 KHz
Project 3a from Rod Elliott is a good amp. He also has an new MOSFET amp that would work well.:smash:
I trust that gainclone is the perfect project for very ambitious beginer. it has very low parts, cheap, and the chip is idiot-proof meaning: it takes a nuclear wrhead to destroy it.
Go to national semiconductor and download application notes on LM3875, most of everything you need you can find it there.
Thanks for you help guys I'll Keep You posted on how I get on.
