Lm3886 Help!
Hello all,
I need help in troubleshooting my amp please, kindly help me find out what's wrong with my amp because when i tested it to a speaker the sound that comes out is attenuated and then disappears and reappears back again after a short while. This action gets repeated over and over. What should i be aware of guys? Equipment used: Rotel ra-02 as preamp LM3386TF Amp is based on "A minimalistic chip amplifier" by Mick Feuerbacher http://tinyurl.com/3resamp Tested to a single 4 ohm woofer Power supply: 220v ac/ 18vdc, bridge rectifier, and 2 cans of 15,000 uf caps |
