just put speaker protection and delay between ouput to spkr terminal if you want protection. there are lots of schematics on this forum.

Michael is referring to 'short circuit protection'. But then many DIY Amps do not have short circuit protection designed into them. Many audiophiles believe that such 'limiting' circuits have a negative sonic impact.

Send me mail and i'll send you article on Safe operating area protection.

You certainly don't want to use simple short circuit protection as it really needlessly limits the amplifier's output current while hardly providing any protection.
