<DIV><FONT size=2>I work on audio amps all the time.</FONT></DIV>
<DIV><FONT size=2>check all caps in the audio amp.</FONT></DIV>
<DIV><FONT size=2>a leakely cap can blow transistors.</FONT></DIV>
<DIV><FONT size=2>IF push pull transistors use a matched pair for</FONT></DIV>

<DIV><FONT size=2>Check emmiter resistors also.</FONT></DIV>
