Im working on a stetsom model # 5k2 e
this unit in going on protection mode, and
if I diconnect the 8 rectifier, protection
goes away. one of the 8 irfp90n20d was
leakage, and was replaced, I disconnected
all audio transistor {irfp90n20d} and power
up the amp, but no difference, no other transistor
was shortage or leakage, any idea on how to
troubleshoot this amp. thanks in advance.

Here are 3 pictures of this amp. by the way I was having
a fail err when try to up load this pictures, I then open this
picture with the paint program the comes with wndows,
save them, and that did the trick for me, hope this can help
others.

No square wave on the power supply either,
but there is no valtage at the power supply rectifiers.
I notice there is valtage for just 1/2 second, at this
rectifiers. here are some pictures of the schematic.
