Can't take the amplifier board from cabinet
Hi, My Fostex doesn't work recently. When I turn the power on, I can see the woofer was pushed back immediately, and the speaker gave low frequencies hum.
I want to take the amplifier board out. I loose all the screw on the board, but it looks the amplifier was sticked to the cabinet by glue. What is the trick to take the amplifier board out?

The reason the woofer is pushed back is the power amplifier is sending DC voltage to it. This means that you have some kind of failure in the amp and need to have it serviced before you burn up the woofer, if you haven't already.
