audioguru Posted November 17, 2005 Report Share Posted November 17, 2005 [move]The amp probably has a shorted output that is causing it to draw too much supply current, get too hot and shutdown.[/move] Quote Link to comment Share on other sites More sharing options...
jeevan772006 Posted November 18, 2005 Author Report Share Posted November 18, 2005 thanks for your suggestion but there is no short output on the amp. Quote Link to comment Share on other sites More sharing options...

Shahriar Posted November 19, 2005 Report Share Posted November 19, 2005 Dear jeevan772006 Once I had made a distributor Amplifier with NE5532 IC. I had the same problem, after a few hours I found that I had not Place one of Jumpers which was related to -Vee Rail. So All of ICs didn't have a -Vee. As soon as I connected it everything went right!!! I was really surprised How it was working... ???I don't know Wether your circuit has any -Vee or not, I just told this to remember Sometimes strange things happen... ;DHTH - Shahriar Quote Link to comment Share on other sites More sharing options...
