How do you remove the amp head from a Fender Rumble 100 combo?

I have a Fender Rumble 100 watt bass amp that was working fine until someone tried to test a head with it. The guys at the local guitar shop said it sounded like a fried transistor but they couldn't fix it. It turns on but doesn't produce any sound. I know a small bit about electronics and attempted to remove the amp from the cab but was unsuccessful. If anyone can help me figure out how to get the head out, the transistor shouldn't be a problem.

How do you disconnect the leads?

I have the same problem and so far I've only got to the point of getting the amp head out of the cabinet. You need to take out all the screws on the top, including the handle and two screws on the right and left side of the cabinet near the back. Then you have to take the 15" speaker out and disconnect the leads to the LED light, speaker, and tweeter (if you want to pull the entire amp head out).

Hope this helps and if you find out how to fix further, let me know on here. I'll do the same, I'm delving further into it today.
