It's gone! It's gone!

Hi all,
I just finished building a new power amp. The amp was fine while there was no signal. I just hooked on the cd player and switched on. All four output transistors blew the moment the signal came in. Where do I start looking?
Thanks for any help.

schmatic?

Hey, how about a schmatic or model name?

hi
maybe the signal made the amp to oscilate , sometimes this makes the output transistors to blow up

Hi,
I have to check it with a scope for possible oscillations, right?

Jens,
I will post the schematic soon.
