RPW10 amplifier blowing fuses

Texto:

I've got a Klipsch RPW10 subwoofer that's blowing fuses every time I try to power it up. I pulled the amp plate off and couldn't find any obvious shorts. Are there any troubleshooting steps I can go through to determine what's causing it to blow fuses? I have a cheap HF meter and a soldering iron but little experience in electrical diagnostics. I can't find any schematics for it unfortunately.
 
Update: I found what looks like the problem. Looks like this little resistor is shorted by the electrical glue, or burnt out and burning the glue. Any suggestion on getting the glue off the board?
 
Update 2: Found more burnt glue. Looks like something on the vertical board is burning it. Doesn't look easy to get the board off so I can inspect it furthur.[image|535371][image|535370][image|535372furthur.
