back fan is dead but the amp still works.

keep it in the same case or make a new one? its about 400 watts

Keep it in the same case, it works very well. i have owned many of these. still have some parts. the fan is a two speed setup with a big fat resistor to slow it down, the solder cracks from vibration.

I have schematics if you need them.
