There are a lot of problems that can cause the amp to apply DC to the speaker terminals.
Before we go any farther, you should know that this amp stores enough energy to kill. When power is applied, the transistors must be clamped to the sink. After removing power, you MUST wait for ALL LEDs to go COMPLETELY out.
You need to CAREFULLY measure the DC voltage from leg 1 to leg 3 of all of the output transistors (the ones you changed). Post a list of the voltages and circuit board designation (FETxyz) for any that read more than 1v.
Do NOT let the probes short to other pins or to the heatsink when measuring the voltage.
Remember... High voltage and lots of stored energy. Be careful.
